Heat of Vaporization-the amount of heat required to convert unit mass of a liquid into the vapor without a change in temperature. For water at its normal boiling point of 100 C, the heat of vaporization is 2260 J g-1. 2260 J of heat must be absorbed by the water. Conversely, when 1 g of steam at 100 C condenses to give 1 g of water at 100 C, 2260 J of heat will be released to the surroundings.
Useful Constants: 1 calorie = 4.186 J. Latent heat of vaporization of water = 539 cal/g = 2256 kJ/kg. Latent heat of fusion of water = 79.5 cal/g = 333 kJ/kg. Specific heat of water = 1 cal/g = 4.19 kJ/kg. 1 atmosphere = 1.01E5 Pa. Universal Gas Constant, R = 8.31 J/mol.K. Boltzmannâs constant, k = 1.38E-23 J/K.
