Homework Help: Heat of fusion - Please Help

  1. Nov 27, 2006 #1
    Determine the final temperature Tf, that results when 77 grams of ice at 0 °C are mixed with 300 grams of liquid water at 50 °C.
    Specific heat of water: c = 1.00 cal/(gram*°C).
    Heat of fusion for the ice - liquid water transition: cF = 79.7 cal/gram

    I have tried this several times and several different ways and cannot solve the answer.

    What are your thoughts on this?

    Apply conservation of thermal energy. Take in the before and after situation and equate the increase of wnergy with the loss of energy.
