A 180 g copper bowl contains 220 g of water, both at 20.0°C. A very hot 300 g copper cylinder is dropped into the water, causing the water to boil, with 5.65 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers with the environment.
(a) How much energy (in calories) is transferred to the water as heat?
(b) How much energy (in calories) is transferred to the bowl?
(c) What is the original temperature of the cylinder?
