1. The problem statement, all variables and given/known data

A Carnot engine working with a monatomic gas operating between two temps, 288K and 497K. The engine performs 800 J of net work.



2. Relevant equations

Q = nRT ln (V final/V initial)


3. The attempt at a solution
I don't have enough info for the above equation. I know I am missing something just not sure what.

What are you to find?

brockjensen

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

[tex]\eta = \frac{W}{Q_H}=1 - \frac{T_C}{T_H}[/tex]


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