# Weird!

A person's body converts chemical energy into internal energy at a metabolic rate of $$100\text{ kcal/h}$$. The person stands neck-deep in an insulated tub containing $$0.8\text{ m}^3$$ of water at $$20^\circ C$$. Disregarding energy loss from the tub, determine the change of water temperature in 45 minutes.

Specific Heat of water is $$1 \text{ cal/g}^\circ C$$.

(Answer In $$^\circ C$$)
