How is water made?

A:

Quick Answer

Water is formed when oxygen and hydrogen atoms combine, and it takes a total of three atoms to make a water molecule. Two of the atoms are hydrogen and the last atom is oxygen, hence the chemical formula H2O.

The purest form of water is free of smell, taste and color. Water is one of the few elements that exists in three different states of matter - solid, liquid and gas. Water becomes a solid, better known as ice, when the water molecules are at a temperature of 32 degrees Fahrenheit or lower. Once it gets cold enough, the water molecules move away from each other, resulting in a solidified form. Contrarily, when temperatures reach 212 degrees Fahrenheit or higher, the molecules move closer together and turn to a gas, also called steam. After water evaporates, it joins with dust particles floating around in the air. During warmer climates, the vapor-dust combination becomes rainfall, and in cooler climates, it turns to snow or hail.

However, it is vital that water be treated before ingesting, because it tends to pick up pollutants. The best way to disinfect water is by circulating it through chlorine and other chemicals that kill unwanted germs. Water is crucial to the survival of animals and humans alike. Without the right combination of oxygen and hydrogen atoms, humans are unable to live.
