Water is a living source for all organisms, and its importance can’t be compared with other liquids. It is having the quality to remove your thirst and gives you satisfaction that cannot be experienced with others. Suppose, you are so thirsty that you are unable to talk, but water is not present, then you drink juice to satisfy your thirst. The juice never takeover the use of water as it has sugar that makes you more thirsty. Water is the only liquid that can satisfy your body demands like for breathing or removal of carbon dioxide. It has numerous qualities that are still unknown by the people.

Adhesion is only shown by the

Adhesion is only shown by the water, that’s why water is considered superior to other liquids like juices, shakes and soups. It allows water to interact with different types of molecules that have different structures as compared to water. In plants, water is required by every part, so it reaches to them by using adhesion quality. Water interacts with the roots, then moves forward, and reaches to the required part of that plant by interacting with numerous components of it. Juice can’t serve this purpose because of the lack of fluidity which is present in water.

If you are drinking other supplements

If you are drinking other supplements of water to fulfil your body demands, then you have to drink them in large quantities. The reason behind is the less amount of water present in its supplements like juices or soups. Water creates an urge for excretion while others can’t do this as they lack fluidity. Juices are bulkier, and contains fats as compared to water, so if an organism is drinking several glasses of juice, then that person never feels hungry. Cohesion is another quality of water that allows it to bind with the same molecules, it means that two water molecules are combined by cohesion.

When an empty glass is filled with water at the top, it doesn’t leak immediately like a tea. These water molecules remain bounded to each other for some time due to cohesion quality, and they form a dome shape which is temporary. This thing is responsible for creating tightness at the top of water in glass that allows a fly to sit on it. It is also a reason for the movement of certain animals on water as it acts as a stretched surface like a fiber sheet. This is a scientific explanation, but this feature doesn’t apply to water in normal life. The foot of an individual holds the overall weight of that individual, water never holds this weight on its surface.

It can be possible if an organism tries to apply the pressure on this water layer by moving at high speed. Scientifically, it is possible by applying certain physical laws like the third law of Newton says that when you pull an object, it also pulls you backward. Similarly, when you slightly keep your foot on water, then its tight membrane applies a force on your foot, that can help you to run on water. This is a rare case because the size of an organism plays an important role as a heavy person can’t run on water. A light-weight organism can run on water because of having low weight that applies less pressure on its surface.

Skiing is a different method by which an organism can run on water by using your feet as skis. This technique requires several years of practice as the chances of getting injured or drowning in water are high. If you want to run, then you have to make long movements while running to prevent the breaking of the stretched layer of water. All types of water sources are not suitable for running as they can harm you, those water areas where water remains free from waves is appropriate for running. Waves destroy your balance, and they lead you to drown into the water. Flowing rivers, lakes or seas can be used as they don’t produce water waves while oceans are the main sources of waves.

These oceans are incomplete without waves, a person can’t run on the ocean water. Drowning can produce the fear in your mind related to water that disallows to use water for any purpose. If you have to run speedily on water, then you have to skip the oceanic water to learn this skill.

Why Water Retains Heat For Longer Periods

Water is a naturally occurring substance that occurs freely in our environment. The most distinguishing feature is the ability to retain heat over prolonged periods of time than most other naturally occurring substances. Every substance, be it air, water, or minerals, has a particular heat capacity which is the amount of heat it can absorb for it to be raised by one degree Celsius. A substance’s heat capacity is determined by its chemical composition, and water, besides it being a liquid, has the highest heat retention above all others.

Each compound has its heat specificity: the quantity of heat needed to raise one gram of a substance by one degree Celsius. Water having a higher heat specificity translates to it requiring an enormous amount of energy for there to be a temperature change. When heating both a piece of iron and water, you will notice that iron will take a shorter time before it’s fully heated. Iron unlike water is a positive molecule with free-floating electrons around its atom that makes it a good conductor of heat.

The structure of water’s molecule comprises

This is attributed to its minimal amount of heat specificity making iron one of the best conductors of heat. Comparatively, water uses a significant amount of time before its boiling point is reached, or when a significant change of temperature is recorded. The comparison waylays that water is a poor conductor of heat as compared to iron, dictated by the movements of their electrons.

The structure of water’s molecule comprises hydrogen and oxygen atoms, with one molecule of oxygen sandwiched by two hydrogen atoms. This results in an unbalanced compound with a slightly negative charge brought by extra electrons from the oxygen atom. Like charges repel each other while unlike charges attract, resulting to water weaker hydrogen bond that keeps on breaking and forming. Because of this chemical structure, water conforms to being a liquid, which then requires a lot of energy for it to be raised by a degree.

The reason why water takes a

If you ever notice while walking on a beach in the summer, the sand heats up faster than water, and may sometimes require treading on the water to cool off your feet. Sand, on having a lower heat capacity than water, takes up heat quickly, and its temperature quickly raised whenever its heat capacity threshold is reached. Having smaller heat retention equals getting heated up quickly, but those with high capacity take some time. The heat specificity of water per gram is 4.186 joules meaning water consumes that volume of energy to raise one gram of water by one degree Celsius.

The reason why water takes a considerable length of time to boil is that heat is quickly spent on breaking the bonds first before heating commences. Breaking bonds of liquid requires a decent amount of heat as compared to solid elements because of the unstable nature of the liquid. They tend to “evade” heat by swirling around in a cycle, making them a poor conductor of heat. Besides, the fluidity of water itself makes it harder for the uniform distribution of heat.

Why Water Retains Heat For Longer Periods

Assuming the source of heat is from a single source direction, then the first cold layer will be heated first, gets lighter, then give way to a denser cold-water layer. This will then repeat several times before the layers are uniformly heated. The characteristics that make water take a long time to heat also make water a good retainer of heat. After the temperature of the water has been raised significantly, it takes time to disperse the same energy off its electrons. A practical example of this is when swimmers feel colder outside water in the evenings just as the sun is going down.

The heat retention of water has enabled it to hold heat for longer periods by making it harder for water to quickly warm up and disperse heat too. This feature has made water a perfect medium upon which marine life comfortably lives. If water had so much temperature change, then it would have been harder for fish to keep adjusting for the right temperatures. Water in the oceans absorbs most of the heat from the sun that plays a big role in moderating the climate around coastal areas. The causative of water holding heat for a longer period is its high heat retention, which makes water take up a lot of energy, before being raised by one degree Celsius.

Depletion of earth water

If all the water on earth could disappear, life would not be possible. Even imagining this situation is scary, considering that even 60% of the human body is composed of water. Water bodies always have water and this provides comfort that water will always be available. Flexing our imaginations a little, let’s imagine and focus on the possibility of all the water disappearing. This work investigates while providing reasons as to why this idea of earth without water could be a reality.

A quick reference of science about

A quick reference of science about how water disappears and re-appears is a good start, a process known as the water cycle. Most of the water on earth is held in oceans, seas, lakes, dams and other water bodies. If we drained these water bodies completely, the remaining amount of water would not be adequate to support life on earth. Statistically speaking, water bodies harbor 91% of all earth water, this is a clear indication of the importance of the oceans as a storage of earth’s water.

Focusing on how most of earth's

Focusing on how most of earth’s water could disappear, it is important to consider ways in which earth water disappears. Earth is made up of matter; matter is anything that occupies space and has mass. Existence of matter is in three distinct states: gas, liquid, and solid. Each state can be converted to each other, when subjected to changes in temperature. In the case of earth water disappearing, we will first consider the ways in which the liquid state is converted to other states. Heating water converts it into hot air called vapor, this is called evaporation. Cooling water converts it to ice through freezing, the opposite of freezing is melting solid state back to water.

Depletion of earth water

Climatic conditions influence temperature affecting oceanic water through seasonal changes where seasons influence temperature. Winter may lower temperatures to low degrees of about ?89.2 °C, while heat may increase to 56.7 °C. Adverse climates are the major converters of water into the other two states. A brutal cold climate results in freezing that converts most of the water into ice. This is common around the Arctics and polar regions, Himalayas is a good example where extreme freezing occurs.

Due to low temperatures, water is stored in glaciers in countries like Antarctica and Greenland. Seasons like winter create extremely freezing climatic conditions that risk disappearance of earth water into solid state. The opposite is also true, an adverse hot climate leads to evaporation of oceanic water. Disappearance of oceanic water is accelerated by the wide surface area of the ocean as well as sun’s heat that accelerates the conversion of more water molecules into gas. Although one would argue that clouds will still fall back as precipitation in water form, back to the ocean, a part of it falls on dry land. Out of this, only a little percentage finds it way back into the ocean again. Very hot conditions too melt glaciers reducing the amount of water stored in frozen state.

Apart from the water cycle processes, flora and fauna also contribute in the disappearance of earth water. Every living thing requires water for existence, and this water is provided by earth. Without water, life would be impossible, animals and plants would equally cease existing. Living things do not give earth back the water used to support life, instead, they produce waste. Apart from drinking water to support life, human beings use water in factories, for irrigation purposes in agriculture, and other human activities that reduce the amount of the water in earth. Factories pollute the environment with harmful chemicals that contribute to the depletion of the Ozone layer. Depletion of the Ozone layer means all the sun’s heat will reach the oceans, increasing the amount of water evaporation.

Having analysed the means in which earth water disappears, it is possible to tell under what circumstances all the water in the earth could disappear. Adverse climatic conditions seem a heavier means of depleting earth water compared to human factors. Practicing sustainable development is among efforts of averting the disappearance of all water on earth. People are encouraged to support afforestation efforts that seek to plant more trees so that we do not lodge ourselves into the effects of adverse climatic conditions. Caring for the environment should be a basic priority for every human being.

Do Aquatic Animals Get Thirsty?

Without a solvent, the chemical processes that occur in living organisms’ bodies cannot proceed, which can pose great danger. Water is essential in the body as it plays the role of being a solvent. Fish being a living organism, require water to help with these chemical processes. Whereas humans and several other animals meet their water needs by drinking, fish uses an entirely different method. They absorb water through the gills and their skins naturally while in water. How this happens is a complex process that should shed some light on an important process known as osmosis.

Fish, unlike mammals, cannot survive on land but live under the water. Whereas you as a human being would find it hard to live in water due to physiological complications, fish finds itself too comfortable with aquatic life. There are basic differences that make it easy for fish to live underwater easily and not human beings. How fish absorb water into the blood system is one of the processes that differentiate these two species. For fresh-water fish, their bodies are saltier than the freshwater they swim in. Their bodies are more saline, water is drawn through the gills, and skin into the body through osmosis.

Fish, like any other animal, need

Osmosis is a process by which water is made to flow from low concentration areas to areas of high concentration through membrane layers. A fresh-water fish with more saline body chemicals will allow water to flow into the body through the membranes. Water will flow from low-concentration water it is swimming in into the more concentrated body solvents of the water animal. Do fish get thirsty to want to increase water intake? Owing to the environment they live in, fish only naturally will have to be equipped with means of living under the water. As a human being, you can’t live under the water too long, or it can turn fatal.

Fish, like any other animal, need oxygen to live, or they will die from deoxygenation. Osmosis is not a means of quenching their thirst as mammals do because fish are never thirsty. Rather, their bodies need oxygen to perform the body’s important functions. While you can breathe in oxygen using the nostrils, fish can’t, but you both need oxygen to survive. In water, oxygen is made of two atoms that are bound together in a liquid form. While fish can derive their gas supply by breaking down this compound, human beings can’t break down the resulting compound and cannot live under the water.

Do Aquatic Animals Get Thirsty?

Osmosis, therefore, involves the absorption of water solutes that contain oxygenated liquid to help fish live. Fish are also cold-blooded, which makes them needless O2. Human lungs don’t have enough surface area to absorb O2 in water as compared to gills. Saltwater fish have a different concept of how their body works, contrary to the freshwater counterpart. The surrounding water is saltier than their body fluids, so they will need to drink water by the mouth. Saltwater fish usually drink water naturally to maintain their marine fluid balance. Their kidney also plays a role in clearing salt from the bloodstream and helps them not shrivel up due to too much salt.

Fish’ bodies require a certain concentration of solutes in the bloodstream to function better. Their gills have special cells that pump in or out salt from their vessels depending on how lowly or highly concentrated they are. The freshwater fish constantly pump in salt to increase the salinity while their counterparts pump out salt to reduce the accumulation. All works by diffusion, which means the accumulation of solutes determines the flow of water. It is just like submerging one potato slice in freshwater and another in saltwater overnight. The potato in salt water will be crunchy by morning while the other counterpart will be soft.

The process for both types of fish is the same, the difference arising from the accumulation of water solutes. Fish cannot literally drink water like humans do but will allow water to flow in between their environments. The diffusion of soluble chemicals helps sustain them in water and makes them breathe. As such, fish are aquatic by nature and better adapted to survive in aquatic conditions.

How Air Causes Objects To Float

Leaves will generally float on water due to their structural formation. They are made of living cells and air spaces that they use for capturing air from the atmosphere. Trees are known to fuel photosynthesis, a process that replenishes the earth’s atmosphere with oxygen. Oxygen is required by all living organisms to survive, without which the ecosystem is likely to be wiped out. Trees through the leaves play an essential role in keeping the ecosystem intact by replacing the used oxygen. It takes in CO2 and gives out O2 through a complex photosynthetic process. Leaves play a central role in keeping life on earth balanced and are the spark that binds all organisms together by providing the all-important gas.

Leaf anatomy consists of layers of specialized cells whose function helps trapping CO2 from the atmosphere. The mesophyll layers being spongy, are infused with the gases carbon dioxide and O2. These gases infused into the leaves cause them to float on water. On draining gases from the spaces, leaves will no longer float since they become denser than water. The concept behind this mechanism in causing various items to float is not new. Think of floaters used by swimmers to float on water; they are usually filled with air.

If a container's volume is 150

When objects sink, they prove that they are denser than the water, a concept that is being used with different processes. There are so many inventions being used today that have adopted the same concept. Air balloons, planetary balloons, super-pressure balloons, zero-pressure balloons, and several others use this same technology to perform great climbing works using balloons. Objects with tightly packed molecules are denser than those with loosely hanging molecules. Why objects filled with air tend to be less dense can be explained by its scientific formation. Air occupies just 1/10% of its volume.

If a container’s volume is 150 cubic metres, air will only occupy 15 cubic metres while the remaining volume will be a vacuum. When you clap your hands, a sharp sound will be produced, caused by squashed air particles trapped in between your palms. Therefore, the air is a sparsely packed object, so it is used in floating effects in several industries and social settings. Plants use carbohydrate molecules manufactured by photosynthesis to grow and replenish themselves. By taking solar energy and converting it by photosynthesis, plants can produce carbonated particles needed for growth.

How Air Causes Objects To Float

Carbon dioxide is used in this process to break it down, remove the CO2 and release the oxygen into the airspace. Plants also convert CO2 into organic chemicals that can be used by plants to grow. These organic compounds are more environmentally healthy than any other energy source because they never contain harsh chemicals as fossils do. Leaves are often known as sinks, similar to heat sinks that absorb excessive heat from ICs in electronic products. The process by which leaves consume CO2 from the atmosphere, break it down to form other useful compounds, helps relieve the air of CO2. CO2 also forms the organic carbon in the oceans to assist marine life.

Every part of this complex ecosystem depends upon each other for survival, making all animal and plant life to become interdependent. As leaves perform these conversions from carbon dioxide to carbonated particles, it balances all gases to render all organisms cohabit. The air spaces found on leaves carry out those trappings of gases by absorbing solar energy and photosynthesizing those compounds from the carbon dioxide gas. After breaking the air molecules, it retains the molecules as an energy source for growth and releases oxygen back to the atmosphere. The air density is far lower due to its sparseness, and that is why leaves can easily float when on water.

Floating is due to those air spaces that trap gases from the airspace to cause the leaves to be less dense. Being less dense, they can float on water because it is denser. Air volume is not compact, allowing a small volume to occupy a large surface area to decrease its weight against other objects such as water. Photosynthesis plays an all-important role in the whole process, an act that keeps the whole ecosystem in tandem for smooth coexistence.
