Homework Statement
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 3.50×10−2 kg .
Throughout this problem use Lf = 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?
Homework Equations
W = Q-ΔEint
The Attempt at a Solution
I calculated Q = M * Lf
3.50*10^-2 * 3.34*10^5 = 11690 J
then I don't know what to do..
please help me..
thanks in advance
