A 180 g copper bowl contains 185 g of water, both at 20.0°C. A very hot 300 gcopper cylinder is dropped into the water, causing the water toboil, with 4.80 g being converted tosteam. The final temperature of the system is 100°C. Neglectenergy transfers with the environment.
(a) How much energy (in calories) istransferred 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?
