4. The PV diagram below depicts two equilibrium states (A and B) of two moles of helium gas confined within a piston, which both lie on the same adiabat (a curve which represents a collection of equilibrium states that a system can reach without exchanging heat with its surroundings). You are supplied with a meter stick and a thermometer, so you can determine the volume of the piston and the temperature of the gas at any stage. You perform an experiment that takes the system from state B to state A along that adiabat. P P. Pa Q=0 B (a) Your lab assistant records data on the experiment, but loses track of which state the recorded quantities belong to, and calls them simply states #1 and #2.
