Molecular Composition Of Water And How It Affects One's Life

In life, chemistry provides the framework. Every visible item consists of different elements that join together and form compounds. Even the most essential components of life are made up of compounds, including water. Most people believe that water exists for drinking and swimming purposes only, but water serves a greater purpose. Without water, life would cease to exist. The distinct molecular composition of water allows it to possess four important and unique properties that help sustain life: cohesive behavior, moderation of temperature, ability to expand when frozen, and the ability to dissolve almost anything on Earth.

Have you ever noticed how water forms droplets and puddles instead of being single rain drops? Each water molecule consists of one negatively charged oxygen and two …show more content…
Transpiration plays a key role in the water cycle because it releases water back into the cycle, so the water can return to the starting point of the cycle, in the oceans. Without cohesion, the water content of the ocean and annual rainfall amounts would decrease (Campbell …show more content…
Very few substances become less dense when they transform into a solid, and water is one of them. When water starts to freeze, the hydrogen bonds widen and form air pockets, making the ice less dense. The molecules also form a different structure from the liquid form of water. The frozen molecules form a lattice type structure, instead of randomly being placed (Water Density). If water weighed more when solidified, ice would sink and freeze ponds and other bodies of water completely, obviously killing off any marine life. The sheets of ice that do form over water helps protect the water from temperature changes when the warmer seasons start to approach (Campbell
