It is a damp, chilly day in a New England seacoast town suffering from a power failure. To warm up the cold, clammy sheets, Jen decides to fill hot water bottles to tuck between the sheets at the foot of the beds. If she wishes to heat 3.0 L of water on the wood stove from 20.0° C to 80.0° C, how much heat must flow into the water?
