For water, the heat of fusion is 80 cal/g. So in other words, this is how many calories are needed to melt 1 gram of water that is frozen. Conversely, when you freeze 1 gram of water, you remove 80 calories of heat from it....
So, you multiply the calories needed to unfreeze a gram of water by the number of grams you have. In this case, 80 * 25 = 2000 Calories

∙ 13y agoIt takes 80 calories per gram ( that is called the heat of fusion of ice)
80 x 25 = 2000 grams

Why do you use Calorie instead of calorie?
A Calorie with a capital "C" is 1,000 calories with a little 'c'. Nutritional guides on food products measure Calories. A calorie is the amount of energy required to raise the temperature of one gram of water one degree celsius. Normally when you eat food it gives you energy. If you eat 1 Calorie of food, it is enough energy to heat one kilogram (2.2 pounds) of water one degree celsius. Jus to maintain your body temperature, you need to eat a lot of Calories. On the other hand, if you eat a 10 gram ice cube, your body has to raise the temperature of the ice from 0 degrees celsius to 37 degrees celsius (body temperature). You will burn 370 calories in the process, but that is only .370 Calories.
