## Work and Internal Energy

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

### Work and Internal Energy

Are we supposed to know the relationship between work and internal energy already? It doesn't seem like we have gone over work, internal energy, or the first law of thermodynamics much in lecture. For example, on 8.3 in the 6th edition, it asks to calculate the work done in the compression and internal energy of the system. Is this something I am supposed to know already?

I don't think we've covered thermo or work yet?
