A 160 g copper bowl contains 180 g of water, both at 22.0°C. A very hot 370 g copper cylinder is dropped into the water, causing the water to boil, with 9.07 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers with the environment. (a) How much energy is transferred to the water as heat? (b) How much to the bowl? (c) What is the original temperature of the cylinder? The specific heat...
