2.4. Calorimeter problem to find the specific heat of lead: If 110 g of lead shot at 120°C is dropped into 60 g of water at 25°C contained in a copper calorimeter of 45 g mass, what is the resulting temperature? [Given: Cwater = 1 cal/g/°C; Cpb = 0.031 cal/g/°C; Ccu = 0.093 cal/g/°C]
1) For part A, calculate q (the heat lost in calories) for copper and lead. The specific heats of these metals are in the background section. Then calculate q (the heat gained in calories) for the water in each case. Remember that you used 25.0 g of water in the experiment. Show your calculations 2)The heat lost by the metal and the heat gained by the water should be the same. Are they? If not, list possible sources of error....
