Water is Essential to Life

Water is Essential for Life Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. It’s important to understand and examine the water molecule in order to ascertain how it brought about Earth’s thriving ecosystem and how important it is for us today. Water is a strong solvent, it’s a very unique molecule that can breaks and reforms constantly. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom also called the “apex of the water molecule” bears a slight electronegative charge while hydrogen possesses a more positive one (Kirk 225). Because of the opposite charges attract, the water molecules are drawn together. When an oxygen atom is linked to a molecule’s hydrogen atom, a bond called a hydrogen bond is formed (Kirk 256). There are several types of water molecule such as liquid water, ice and water vapor. These are all as important as we need in our daily lives. In a liquid form of water it has no such spaces because hydrogen bonds constantly breaks and reforms. Thus ice is stable hydrogen bonds that bonded together, it’s less dense and will float on liquid water. If it’s not this reason, the 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 all die (Bio; notes) Water is a very small molecule that has its own unique properties therefore it behaves like a larger one. The bonds between water molecules are the covalent bonds; these bonds are so strong that water resists changes in its state. For example, solid, liquid and gas. Thus water has a higher melting point and a higher boiling point than any other molecule of similar size (Kirk 256). When heat is applied to solid water, some hydrogen bonds get so much kinetic energy that they break and the ice melts. Whereas liquid water does not necessarily have all four hydrogen bonds p…
