A Carnot 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. When 6600 J of heat is put into the engine and the engine produces work, how many kilograms of ice in the tub are melted due to the heat delivered to the cold reservoir? (See Table 12.3 for appropriate constants.)

I'm not sure how to being.
I was thinking about using:
Qc/Qh = Tc/Th but i'm not sure :yuck:

If you know the reservoir temperatures and the heat input to a Carnot engine, you should be able to calculate the heat output. What equations do you have for the efficiency of a Carnot engine?
