Calculate the specific heat of a metal from the following data. A container made of the metal has a mass of 3.3 kg and contains 15 kg of water. A 1.0 kg piece of the metal initially at a temperature of 170°C is dropped into the water. The container and water initially have a temperature of 16.0°C, and the final temperature of the entire system is 18.0°C.
