High heat of vaporization of water
WebThe Heat of Vaporization (ΔHvap) 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. … WebThe enthalpy of vaporization(symbol ∆Hvap), also known as the (latent) heat of vaporizationor heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressureat which that transformation takes place.
