How do you derive pV=31Nmc2ˉ and what assumptions do you have to use? I can derive Pv=nRT. I then use U=3/2 kT but I don't know how to derive that so I'm not sure I am going down the right route.
this is a struggle to remember but its something to do with kinetic energy is the same as temperature and e = mc^2 that may be random facts mixing together in my head though!
