## expansion work

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

### expansion work

in expansion work the volume increases. does the pressure change or is it constant at 1 atm?

### Re: expansion work

In expansion work the pressure is usually constant and given in the problem; therefore the equation is work=−PΔV.
