## 8.16 Constant Volume

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

### 8.16 Constant Volume

Closed System with Constant Volume.
Always True, Always False, or True Under Certain Circumstances:

1. delta u=0
2. w=0
3. w<0
4. delta U=q
5. delta U=w

I am confused on this and do not know the answers

### Re: 8.16 Constant Volume

This is what I got when I tried the question:

1. True only when heat isn't transferred to/from the system (q=0)
2. Always true (because volume isn't changing)
3. Always false (work=0 because delta V=0)
4. Always true (because work=0)
5. True only when heat isn't transferred to/from the system (q=0); delta U=w=0 in this case because there is also no change in volume.
