Water

Water is used all around us everyday and is essential in the maintenance of life. Water is a requirement of the human body for the smooth functioning of body systems. Substituting other fluids for water can negatively impact one's health, especially in the case of children. Children who drink juices in the place of water have a tendency to be overweight and are at risk for other problems associated with "normal" growth. For teens and adults, reliance on fluids other than water also has side effects. For example, the sugar in soda contributes to tooth decay in teens, while in adults, the phosphoric acid can ultimately diminish bone density.

Water is an odorless, tasteless, and transparent liquid. It may look colorless in small amounts, but in large amounts such as an ocean, it looks slightly blue. Water is the most common liquid on earth. Three-fourths of earth's surface is covered with water.

Water is made up of two atoms of hydrogen and one atom of oxygen. Each hydrogen atom is connected to the oxygen atom by a covalent bond. The two H-O bonds form an angle of about 105 degrees. This arrangement results in a polar molecule. A polar molecule is a molecule with a net positive charge at the hydrogen ends and a net negative charge toward the oxygen end.

This substance has a great amount of surface tension. Surface tension is a result of the water molecules clinging tightly together. This surface tension is responsible for causing a leaf to float on top of the water. The only liquid with a greater surface tension than water is mercury. Mercury's atoms are so attracted to each other that they tend not to adhere to anything else. Therefore, mercury's surface is able to hold heavier objects up, unlike any other liquid.

Vaporization, or evaporation, is the change of a liquid to a gas. Water has a high heat of vaporization. At water's boiling point, it takes 540 calories to change 1 gram of liquid water into vapor. Hydrogen bonding also plays a role in water's high heat of vaporization. Vaporization comes from the rapid moving molecules. These molecules break loose from the surface and enter the air. The hotter the liquid, the faster the molecules move. Therefore, the hotter the liquid gets, the more vaporization occurs.

    The world as we know it would not be the same without water. If every lake, river, and ocean were emptied and filled with something other than water, life itself would not exist. This is due to water’s unique molecular structure and arrangement due to its bonds. Water is a molecule made up of two hydrogen atoms and one oxygen atom: H2O. The hydrogen atoms have a partial positive charge and the oxygen atom has a partial negative charge. In water’s molecular structure, there are two unshared pairs

The water cycle is the continuous movement of water on, above and below the surface of the Earth where water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In this process, the water goes through different phases: liquid, solid and vapour. Water cycle involves exchange

    Water is not as simple as people think it is. Water is formed by the bonding of two hydrogen atoms and one oxygen atom. This bond that is being referred to is termed as a polar covalent bond. Polar means having a pair of equal and opposite charges. In this case, that is exactly what is happening. The oxygen atoms are negatively charged, whereas, the hydrogen atoms are positively charged. Water is formed when one atom of oxygen joins with two atoms of hydrogen which causes the ends of water molecules
