When you mix two substances that are initially at different temperatures, the hotter substance cools and the colder substance warms until they reach a common temperature. Then the substances are said to be in thermal equilibrium. For our purposes assume that the heat is exchanged only between the hot and cold materials and that no heat is lost to the surroundings. The specific heat capacity of water is 1.0 cal/(g Co) and the specific heat capacity of copper is 0.092...
