No constant P or V

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

No constant P or V

Will there ever be questions of W, delta S, etc where you will have no constant p or V. If so, what are some examples within the book which have these problems?

Re: No constant P or V

You could have a process which is isothermal (constant T). For these cases you calculate the work with W = -nRTln($\frac{V2}{V1}$)

I do not know of specific problems, but look for the word isothermal and that should help. The problem solving process is the same as for isochloric and isobaric processes. W is the area under the curve, entropy can be visualized conceptually or calculated for S = Q/T or from G = H - TS
