What are you to find?

Sorry, that would have been helpful.

Need to find heat absorbed and heat released, also efficiency, but I think I got that one

 

[brockjensen]

Yeah that would be helpful huh?

Need to find heat absorbed and heat released, also efficiency but I think I figured that out.

You should know that for a Carnot engine, the efficiency is given by

$$\eta = \frac{W}{Q_H}=1 - \frac{T_C}{T_H}$$


Now that you know this, I think you can easily find Q_H
