A metal object with mass of 20.4 g is heated to 97.0 °C and then transferred to an insulated container containing 80.9 g of water at 20.5 °C. The water temperature rises and the temperature of the metal object falls until they both reach the same final temperature of 22.7 °C. What is the specific heat of this metal object? Assume that all the heat lost by the metal object is absorbed by the water.
