A calorimeter cup is made from 0.15kg of Aluminum and contains 0.20 kg of water. Initially, the water and cup have a common temp of 18-degree Celcius. A 0.040 kg mass of unknown material is heated to a temp of 97-degree Celcius and then added to the water. The temp of the water, the cup, and the unknown material are 22-degree Celcius after thermal equilibrium is reestablished. Ignoring the small amount of heat gained by the thermometer, find the heat capacity of the unknown material.
