An ideal gas at pressure p is compressed isothermally until the mean separation between molecules is one-third of the original. Find the final pressure in units of p.

Answer:

Solution:

Mean separation $\propto V^{\frac{1}{3}}$ , so the volume falls

to $\frac{1}{27}$ . At constant $T$ the pressure becomes $27 p$ .
