A gas obeys $P^{3} V = constant$ . Starting at $T_{0}$ and $V_{0}$ , it expands to $8 V_{0}$ . The final temperature is:

Options:

Answer:

Solution:

$P = \frac{n RT}{V}$ gives $\frac{T ^{3}}{V ^{2}} = constant$ , so $T \propto V^{\frac{2}{3}}$ . For $8 V_{0}$ : $T = 8^{\frac{2}{3}} T_{0} = 4 T_{0}$ . B.
