(7%) Problem 5: A 97.4-g aluminum calorimeter contains 250 g of water. The aluminum and water are initially in thermal equilibrium at a temperature of 9.1.C. Two solid objects are then placed in the water. One is a 48.3-g piece of copper with a specific heat of 390 J/(kg. C) and an initial temperature of 79.7.C. The other is of unknown material with a mass of 71.9 g and an initial temperature of 100 C. The entire system reaches thermal equilibrium at a temperature of 19.6 C. The specific heats of aluminum and water are 910 J/(kg. C) and 4186 J/(kg. C), respectively. Shah, Isha - shahis17@students.rowan.edu Find the specific heat of the unknown material, in units of J/(kg. C).
