A 1-m3 tank containing air at 25 o C and 500 kPa is connected through a valve to a second tank containing 5 kg of air at 35 o C and 200 kPa. When we open the valve we let the system to reach thermal equilibrium with the surroundings, which is at 20 o C.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
