Detailed explanation-1: -That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Water’s heat of vaporization is around 540 cal/g at 100 °C, water’s boiling point.
Detailed explanation-2: -Heat of Vaporization of Water Water has high specific heat. This measurement describes the amount of energy it takes to raise the temperature of water 1 degree Celsius. As such, water also has a high heat of vaporization. In fact, water takes over 40, 000 Joules per mole to vaporize.
Detailed explanation-3: -The heat of vaporization of water is the highest known. The heat of vaporization is defined as the amount of heat needed to turn 1 g of a liquid into a vapor, without a rise in the temperature of the liquid.
Detailed explanation-4: -High Heat of Vaporization The Heat of Vaporization (Hvap) is the amount of energy to convert 1g or a substance from a liquid to a gas. In order for water to evaporate, hydrogen bonds must be broken. Water’s heat of vaporization is 540 cal/g. In order for water to evaporate, each gram must GAIN 540 calories .
