Water used to be considered an element itself and was not considered a compound until 1781. Water is odorless and tasteless liquid, but water can be in forms of solid and gas. Water is needed to be consumed by all humans so we will not dehydrate. Not only humans need water, but all living organisms. Our bodies are 65 percent of our bodies volume and the earth is 70 percent water.
Water is also one of the best-known ionizing agents.
Most substances are somewhat soluble in water so it has been given the name of universal solvent. Water is the only substance that exists in at ordinary temperatures in all states of matter, solid, liquid, and gas. In the solid state the water molecules are interacted with each other very strongly and the volume expands. In the gaseous state, water molecules are very much separated from each other. Collisions of water molecules in the gaseous state is very unlikely.
