Melting Ice with a Carnot Engine

  1. Dec 11, 2007 #1
    1. The problem statement, all variables and given/known data

    A Carnot heat engine uses a hot reservoir consisting of a large amount of boiling water and a cold reservoir consisting of a large tub of ice and water. In 5 minutes of operation of the engine, the heat rejected by the engine melts a mass of ice equal to 3.30×10^-2 kg.

    Throughout this problem use L_f =3.34 * 10^5 j/kg for the heat of fusion for water.

    During this time, how much work W is performed by the engine?

    2. Relevant equations

    Q= mL

    3. The attempt at a solution
    Q= mL
    = 3.30*10^-2 * 3.34*10^5
    = 11022 J

    and then i am stuck.. what should i do
