The Properties and Characteristics of Water

Decent Essays

Did you know that the first cells evolved in water? Today, water makes up seventy to ninety percent of all organisms and covers seventy-five percent of the Earth’s surface. It is used every day for cooking, cleaning, drinking, powering, cooling, ect. As humans, we cannot even go for more than a few days without it. It has been and still is a necessity for life, and without water’s versatility and other unique properties, existence as we know it would be impossible. (Mader, 2013)
Water is able to exist as a solid, gas and liquid at normal Earth temperatures and pressures, making life possible. It is a small molecule that consists of two hydrogen atoms and one oxygen atom. In liquid water, “the molecules are chaotic, jumbled and packed densely together,” but as ice forms, the molecules slow down and arrange themselves in a crystal structure. The spaces between the molecules in the crystal structure are what make it feasible for ice to float on water. However, salt water takes longer to freeze than fresh water because the presence of salt causes the water molecule to take longer to slow down. When water goes from a solid to a liquid, melting occurs. However, sometimes a solid goes directly to a gas or vice versa, which is called sublimation. Nonetheless, when the bonds break between molecules of liquid water, they evaporate into the air. In water vapor, gas, the spaces between molecules are larger than the molecules themselves. Condensation transpires when water goes from a
