## Deriving Equations for Work [ENDORSED]

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

### Deriving Equations for Work

Do we need to be familiar with the exact steps to derive the equations (using integrals) for work of irreversible and reversible processes as well as entropy?

It would be useful to know the derivations for the purpose of understanding how we arrived at the 2nd Law of Thermodynamics, but hopefully Dr. Lavelle will clarify this before the midterm.

Derivations will not be tested on the quizzes, but they are possible for the midterm and final. They also help with understanding of the problem.
