## Reversible process

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

### Reversible process

Why do we use integrals to find w?

### Re: Reversible process

W is found using integrals because integrals add up the tiny increments of change in volume during expansion.

Because work is defined as the energy transferred from one type to another whenever a force is applied causing an object to move a distance.Work would be the area under the graph on a force-displacement graph.
