We've been set the question of- In an isothermal expansion, and ideal gas at initial pressure Po expands until its volume is twice its initial volume. When the gas is compressed adibatically and quasi-statically ack to its original volume, its pressure is 1.32Po. Is the gas monatomic, diatomic or polyatomic? How does the translational kinetic energy of the gas change in these processes? We can assume throughout that the gas is in the regime where rotational motion takes plae, but vibraional motion is frozen out. I wouldnhave said that the translational minietic energy increased throughout, but how specific would I need to be really? Also, I have no idea about what type of gas it is. Any help would be much appreciated. Thanks!
