1 calorie (small "c") is the amount of heat needed to raise 1 g of water by 1 degree. We have 100 g of water, and the temperature went up by 20 degrees. Therefore, the number of calories is as follows:
100 g H2O x 1 cal/gº x 20º = 2,000 calories

The question asked for calories (small c) not nutritional calories which is why I made the differentiation.

But "nutritional calories" are written as Calories (big "c") are actually kilocalories. So 2000 calories (science calorie, little "c") is 2 kcal, which is the same as 2 "nutritional calories". "2 Calories" Hope that makes sense, it was probably a mini-marshmallow! :D10/01/21
