So if we have a gas at a temperature T, these things are supposed to be true:
1) Regardless of if it is real/ideal, the KE is supposed to be the same at T
2) If the gas were real there would be lower pressure because of intermolecular forces, reducing collision with the walls of the container
But don't these two concepts sort of contract each other? With 2 I think of the velocity of the real gas being decreased due to intermolecular forces pulling the molecules towards each other, thus causing reduced pressure. But wouldn't this cause decreased KE for the real gas as well? How can KE stay the same with pressure reduced?
