A copper beaker of mass 0.20 kg contains 0.10 kg of water at 20.0 celsius. A block of silver of mass 100 g at 90.0 celsius is added to the beaker of water. The entire system is thermally insulated from the surroundings.(specific heats-copper: 390J/Kg K, silver: 234 J/ Kg K, water: 4190 J/Kg K)
(a) What is the final temperature of the system?
(b) What is the heat lost by the silver?
(c) What is the heat gained by the water? What is the heat gain of the copper?
