Question

Latent heat of fusion of ice is 80calorie / gram . What do you mean by that?

Answer 1

• This means that 1 gram of water at 100° C changes to 1 gram of steam at 100° C by absorbing 540 calories. ... Thus the latent heat of vaporization of water is 540 cal/g/°C and the latent heat of fusion of ice is 80 cal/g/°C. At higher pressures, it takes more than 540 calories for every gram to vaporize.
