2. An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10°C. Two metallic blocks are placed into the water. One is a 50g piece of copper at 80°C. The other block has a mass of 70.0 g and is originally at a temperature of 100°C. The entire system stabilizes at a fixed temperature of 20°C. Determine the specific heat of the unknown material. Given: CAL = 0.910 ’/g · c° g C° Ccopper = 0.390%a.c Cwater = 4.186 %a• c° g
