Explanation:
Detailed explanation-1: -Water continually evaporates, condenses, and precipitates, and on a global basis, evaporation approximately equals precipitation. Because of this equality, the total amount of water vapor in the atmosphere remains approximately the same over time.
Detailed explanation-2: -Approximately 600 calories of heat must be added to a gram of water for it to evaporate into the air. This energy is called “the latent heat of vaporization". Latent heat is used to break the hydrogen bonds that bind water molecules together.
