Imagine that your water heater has broken, but you want to take a bath. You fill your bathtub with 25 kg of room-temperature water (about 25 C). You figure that you can boil water on the stove and pour it into the bath to raise the temperature.

1. How much boiling water would you need in order to raise the bath to body temperature (about 37 C)? Assume that no heat is transferred to the surrounding environment.

Start forming equation with the informations and that you know heat gained = heat lost.
