X is half the original pressure.
A diathermic wall differs from an adiabatic one in that Thermal energy cannot pass through an adiabatic wall. Unlike intensive variables, extensive variables depend on how much of the stuff you have. Derive an expression for the average kinetic energy of a single molecule of this two-dimensional gas. Put your answer in terms of k, T, and the mass of a single molecule m . It is consistent.
