  • I'll take a stab at this without looking it up. The heat term needed in this question is calories. It takes one calorie to raise the heat of 1 gram(ml) of water 1 degree Celsius. However, there is a transition to make the solid ice become a liquid. This transition absorbs energy without increasing the temperature. The amount of calories to raise the 100 grams of ice -20 degree C to 115 degrees C is 135 + the amount of heat to turn ice into liquid. Now all you need to do is convert calories to kj/kg
