A 150 g copper bowl contains 220 g of water, both at 20.0 degrees Celsius. A very hot 300 g of copper cylinder is dropped into the water, causing the water to boil, with 5.00 g being converted to steam. The final temperature of the system is 100 degrees Celsius. how much energy is transferred to the water as heat. How much energy is transfeed to the bowl? What is the orginal temperature of the cylinder?
