How to do part biii?
I tried to find change of U and W, then use ΔUW=Q=0.
I can find the change in U by using the fact the rms of the xcomponent of the velocity is doubled. Therefore, originally, if isotropic <c^{2}> = <v_{x}^{2}>+<v_{y}^{2}>+<v_{z}^{2}> = 3<v^{2}_{x}>,
now the new <v_{x}^{2}> is 4 times the old one, so the new mean square <c'^{2}>=6<v_{x}^{2}>=2<c^{2}>, so the new internal energy is double the old one. How about the work done? How to find it? I have only learnt how to find adiabatic, isothermal and constant volume work done.
