A precious-stone dealer wishes to find the specific heat capacity of a 0.036-kg gemstone. The specimen is heated to 95.0°C and then placed in a 0.17-kg copper vessel that contains 0.086 kg of water at equilibrium at 25.0°C. The loss of heat to the external environment is negligible. When equilibrium is established, the temperature is 29.5°C. What is the specific heat capacity of the specimen?
