## Work equations

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

### Work equations

What is the difference between the capital W and lowercase w on the equation sheet?

Big difference! w is representative of work, while W represents degeneracy. They are each used in various equaitons we've looked at in class; work is more related to energy, while degeneracy is closely tied to entropy. Hope this helps! :)

### Re: Work equations

hi miriam! They both represent different things.. the lowercase w is to calculate work done on the system which is used for reversible and irreversible reactions. While, the capital W represents degeneracy, so it used to calculate residual entropy.
