A 135 g copper bowl contains 190 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 5.75 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers by the environment.
1. What is the original temperature of the cylinder?
2. How much energy (in calories) is transferred to the bowl?
3. How much energy (in calories) is transferred to the water a sheet?
