Detailed explanation-1: -Statement 2: The heat of fusion of water is 80 calories per gram or 3.34×102 joules per gram.
Detailed explanation-2: -The latent heat of fusion for ice is 80 calories per gram (see calorie). This amount of heat is absorbed by each gram of ice in melting or is given up by each gram of water in freezing. The latent heat of vaporization of steam is 540 calories per gram, absorbed during vaporization or given up during condensation.
Detailed explanation-3: -The heat required to change a solid to a liquid with no change in temperature is called the latent heat of fusion. For ice/water the heat of fusion is 80 calories per gram.
Detailed explanation-4: -It is also a latent heat and is sometimes called the latent heat of fusion. It has only one value for water, because water freezes at one value (0 °C), and it is 79.71 cal/g or the rounded number 80 cal/g. The high heat of fusion of water is used in frost control.
