Define about the Bell Jar?
A vessel with a small hole of diameter d in it is delegate inside a high-vacuum chamber. The pressure is so low that the signify free path λ>> d.
The temperature of the gas in the chamber is T0, and the pressure is Po The temperature in the vessel is kept at a constant T1 = 4 T0. What is the pressure within the vessel when steady state is reached?
