Calculate the specific heat of a metal from the following data. A container made of the metal has a mass of 3.2 kg and contains 20 kg of water. A1.7 kg piece of the metal initially ata temperature of 170°C is dropped into the water. The container and water initially have temperature of 15.0°C, and the final temperature of the entire system is 18.0°C.
