I was wondering whether anyone was able to give me a hint on the following problem:(adsbygoogle = window.adsbygoogle || []).push({});

Is the average kinetic energy of all particles in a gas hitting the sides of a container less, equal or more than 3/2kT? And if it is not equal how can you calculate the mean kinetic energy?

I was thinking that since the flux and the pressure is the same everywherein the container, the kinteic energy should be the same as well. Thus the average KE is 3/2kT. I'm not really convinced by my argument here. But I can't really find a counter-argument (except maybe that the wall has 2D instead of 3D, but I'm not sure how and whether that would influence the flux or KE of the particles).

Thanks a lot for any hints and suggestions!
