Water is a liquid that dissolves another liquid in itself. There is a very enormous supply of water because it is a natural resource that comes from the Earth. Water molecules are very unique. This is because water has significant properties and the way the structure of water is made up. Water is a type of molecule called a polar molecule. This means that water has one slightly negative oxygen atom and two positively charged hydrogen atoms. This is polarity because the electrons of water are not shared evenly in a sharing bond. Polarity is what causes water to attract or stick to substances. (Resources, n.d.) This type of connection also makes a polar covalent bond because of the tails of the water molecule have attracting charges. (Alan Damon, 2007).
There are a lot of properties of water. One being called the thermal properties of water. High specific heat is one of the properties of thermal. This means that what can captivate or release a well amount of warmth without altering the temperature critically. It takes 4.2 joules exactly to raise the temperature of water by one degree in Celsius (Freeeman).When warmth is absorbed, hydrogen bonds are dismembered and water can mobilize easily. Yet when the temperature of water drops, hydrogen bonds are made and give off a significant quantity of energy. Every living thing is composed of a lot of water. Water acts as a stabilizer for the temperature in organisms. It has the maximum specific heat measurements of any fluid. This makes water an excellent place for that habitat of animals (Boundless, 2011). Water also evaporates at high very high temperature. So this has a lot to do with the climate of the Earth. The ocean takes a longer time to get hotter. Water boiling temperature ...

Water is a very important substance for life. Every living thing on Earth needs water and is consisted of water. Water has many uses for both plants and animals today. It maintains homeostasis for animals and keeps the body working correctly.

Water is the life blood of every living creature on earth. Approximately 70 percent of the earth's surface is covered with water. Through the wonders of nature, water can take on many different forms. It is easy to understand the significance water plays in our lives, but it may be difficult to understand the water that exists below the earth's surface. This water is called groundwater.

... along with the negative lone pair of a different water molecule, termed as hydrogen bonding. This hydrogen bonding is a form of a brittle electrostatic attraction, giving rise to a complicated system of molecules. Thus, water is all the more related to chemistry. In fact, most of the processes and chemical reaction comprises of the molecule of water one way or the other, may that be formation of the solution as a solvent, or may that be the testing of the electronegativity of the substance, every where in the chemistry, we see the role of water. Water is not just related to scientific chemistry, but also related to the chemistry of life, as the life form is more or less comprised and build up of water.

The Biological Importance of Water as a Solvent and as a Medium for Living Organisms
Drinking water is essential and indispensable to life itself possible on the face of the earth, it is much more than a well, a resource, a commodity, drinking water is specifically a human right of first order and an element essential national sovereignty itself and, most likely, whoever controls the water control the economy and life in the not so distant future.
Water Potential: The water potential of a solution is a measure of whether it is likely to lose or gain water molecules from another solution. A dilute solution, with its high proportion of free water molecules, is said to have higher water potential than a concentrated solution, because water will flow from the dilute to the concentrated solution (from a high potential to a low potential). Pure water has the highest possible water potential because water molecules will flow from pure water to any other aqueous solution, no matter how dilute. When two such solutions (one strong, one weak) are separated by a semi-permeable membrane the water will move from the side with more water to the side with less until both sides are equal (have reached equilibrium). This can be seen in all living cells.
Water has a great number of roles in living organisms, this is largely to do with the structure and covalent bonding in a single water molecule, and between water molecules. Around 75% of the earth is covered in water, and it is reffered to as the most important Biochemical. Its chemical symbol is: H2O In a water molecule there are two bonding pairs and two non-bonding pairs of electrons. These four pairs of electrons repel one another, forming a tetrahedral pattern.
Summary: Without water, there is no way that life would be sustainable on this planet. It is without a doubt our most valuable resource.
Cohesive Force: The intermolecular forces that cause liquids to resist separation and to remain a certain shape. This exists between molecules of the same substance.
Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive one. Because opposite charges attract, the water molecules are drawn together. When an oxygen atom is linked to a neighboring molecule's hydrogen atom, a bond called a hydrogen bond is formed. In an ice crystal the hydrogen bonds to give the shape of the crystal so that the grid of molecules surrounds relatively to large spaces. In a liquid form, water has no such spaces; so ice is less dense and will float on liquid water. If not for this, great bodies of water would freeze from the bottom up without the insulation of a top layer of ice and all life in the water would die.
Water is the most vital part of life. Water is needed from humans, to plants and other organisms, and to do basically everything. Water allows our bodily functions to work and to remove waste from our bodies. Plants need water to grow, and humans need plants to gr...

Water is an essential nutrient that our body requires every day. Without water human life cannot be sustained. Water deprivation kills faster than lack of any other nutrient. People do not think of water as a nutrient and don’t realize the important role of water in the body functions.
Water covers about seventy one percent of Earth’s surface. Earth is the only planet to have stable bodies of liquid water on its surface which is crucial for all known life forms. Water is a substance which acts as a solvent in which organic compounds can mix, and it is the substance which is thought to be necessary to facilitate the formation of life. There are many forms of water which include ice, liquid, and gas. Because water can exist as a gas, it can be stored in the atmosphere and be delivered as precipitate. Water also helps regulate the climat...
Water is an irreplaceable natural resource on this earth which comprises marine, estuarine, fresh water (river and lakes), ground water across coastal and inland areas. Even though there is huge water resource in this world, about 97% of water is salt water (marine) only 3% is fresh water. And in this small fraction of fresh water a major part is in the form of ice in polar region. So just 0.003% is in the form of ground water and surface water which we can use.
