Conclusions

Equations have been derived describing the behavior of a spherical pore filled with a constant amount of gas. It is shown that under certain conditions such a pore tends to an equilibrium size. The rate of attainment of equilibrium depends on the relative values of the external pressure, surface tension, and gas pressure.
