Its not joule thomson effect.Its free expansion of ideal gas during which temperature remains same due to perfect thermal isolation

Yes,its possible Check this: http://en.m.wikipedia.org/wiki/Joule_expansion

We all know that in free expansion of gases under adiabatic condition and keeping the temperture constant ,we get that no work is done by the gas.Moreover since del(Q)=0, del(U)=0 according to first law of thermodynamics.But we get a increase of entropy by an amount Rln2.Now the question is that...

Is there any direct experiment to determine the value of mean free path(not the distribution) of a gas molecule?
