Question

How much heat is required to raise the body temperature of a 60-kg woman from 21.9°C to 57.3°C? Units in kcal

Answer 1

Human beings are largely with 99% water as the main composition. It takes about 1 kcal to rinse 1kg water for 1°C. Hence, in this case the required heat is:
60*(57.3-21.9) (kcal)
You please do the math.
