Halliday, Resnick & Walker — Temperature, Heat, and the First Law of Thermodynamics: Problem 56

56 A 150 g copper bowl contains 260 g of water, both at $20.0^\circ\text{C}$. A very hot 300 g 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 $100^\circ\text{C}$. Neglect energy transfers with the environment. (a) How much energy (in calories) is transferred to the water as heat? (b) How much to the bowl? (c) What is the original temperature of the cylinder?
