The specific heat of a certain metal can be determined by measuring the temperature change that occurs when a piece of the metal is heated and then placed in an insulated container that is made of the same material and contains water. Suppose the piece of metal has a mass of 105 g and is initially at 100 °C. The container has a mass of 237 g and contains 457 g of water at an initial temperature of 20.0 °C. The final temperature is 21.4 °C. What is the specific heat of the metal?
