Question 265: Thermodynamics & KTG

Question

A monoatomic gas at pressure $$\mathrm{P}$$ and volume $$\mathrm{V}$$ is suddenly compressed to one eighth of its original volume. The final pressure at constant entropy will be :

Accepted Answer

$$P{V^\gamma }=$$ constant
$$ \Rightarrow P{V^\gamma } = (P'){\left( {{v \over 8}} \right)^\gamma }$$ where $$\gamma  = 5/3$$
$$ \Rightarrow P' = 32P$$

Answer

P

Answer

8P

Answer
