Homework Help: Help with Energy transfer

  1. Sep 23, 2008 #1
    A 125 g copper bowl contains 235 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 5.05 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers with the environment.
    How much energy is transferred to the water as heat?

    I found the heat for the steam, bowl, water, and part of the cylinder except for the initial temp of the cylinder. I don't know where to go from there.
    Qs= 11.39kJ
    Qw=78.772kJ
    Qb=3.86kJ
    Please help.
