4. A copper calorimeter (100.0 g) contains glycerin (220.0 g). Both the calorimeter and the glycerin are at an equilibrium temperature of 27°C. An unknown solid of 150.0 g mass, which is at -75°C is added to this calorimeter. The calorimeter along with its contents reaches an equilibrium temperature of -30.0°C. (a) Calculate the specific heat of the unknown solid. (b) What would be the final equilibrium temperature of the calorimeter along with its contents, when 60.0 g of the unknown solid at -75°C is added to the copper calorimeter (250.0 g) containing glycerin (150,0 g) is at 27°C?
