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.
Similarly, while ice melts, it remains at 0 Â°C (32 Â°F), and the liquid water that is formed with the latent heat of fusion is also at 0 Â°C. The heat of fusion for water at 0 Â°C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 Â°C is about 2,230 joules (533 calories) per gram.
