A 50 gram metal can has a specific heat capacity of 0.1 cal/gC and contains 50 grams of water. These two bodies, the metal can and the water, cool down together from 50C to 30C. The specific heat capacity of water is 1.0 cal/gC. 1. Compute the heat lost by the metal can alone. 2. Compute the heat lost by the water alone. 3. Determine the total heat lost by the system.
