1. A calorimeter (a device to measure heat transfer) is being tested. It consists of a sealed cylindrical vessel containing water placed inside a sealed well-insulated tank containing ice water at 0C. The water in the cylinder is heated by an electric coil so that 1000 J of energy are introduced into the water. Then the water is allowed to cool until it reaches 0C after 15 minutes and is in thermal equilibrium with the water in the ice bath
