A 130 g copper bowl contains 210 g of water, both at 25.0°C. A very hot 450 g copper cylinder is dropped into the water, causing the water to boil, with 16.9 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...
