How much boiling water would you need to raise the bath to body temperature (about 37c )? Assume that no heat is transferred to the surrounding environment. Imagine that your water heater has broken, but you want to take a bath. You fill your bathtub with 25kg of room-temperature water (about 25c ). You figure that you can boil water on the stove and pour it into the bath to raise the temperature
