Does hot water or cold water evaporate faster?
Hot water freezes faster than cold water. Water molecules are composed of one oxygen atom bonded to two hydrogen molecules. When water molecules come in close contact, a natural repulsion between the molecules to stretch and store energy. As the water heats, the hydrogen bonds stretch as the water gets less dense and the molecules move further apart.

Hot climates typically have high temperatures and low humidity, while cold climates have low temperatures and can vary in humidity.
