$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### Proving the work equation

Will we be required to know / explain the integral justification for w = P delta V?

I believe that all the derivations of those formulas are fair game on the midterm since Professor Lavelle went over it in class.

If you remember that it is always the integral of V1 to V2, and depending on the question, whatever are constants you move to the outside of the integral sign, then you should be fine.
