# Surface Area/Pressure/Ideal Gas Law

How does surface area affect pressure, since pressure is defined by $\frac{Force}{Area}$, and specifically how does this work with the Ideal Gas Law ($PV = nRT$)? I would think that surface area and pressure have an inverse relationship, as to pressure and volume. But what if you had gas-filled containers with the same volume but different internal surface areas? I would think that the pressure in the one with less surface area would be less, but this is not evidenced by the ideal gas law.

Pressure is independent of surface area.
