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?
If a particle in periodic motion moves back and forth (or to and fro) over the same path, then its motion it is called as vibratory or oscillatory. The examples of vibratory or osc
