A sealed chamber has an initial volume 0.5 m and contains AIR at temperature 0 C and pressure 1 x 105 Pa. The chamber has one movable wall that can compress or expand the volume without letting any gas escape. The wall is now compressed until the chamber reaches a final pressure of 2.5 x 105 Pa. Consider three possible ways to do this. a.) If the process is isothermal, find the net heat transfer Q. Does this heat enter or leave the chamber? b.) If the process is adiabatic instead, find the work done on the chamber. c.) If the process is isochoric instead, find the final temperature. d.) Sketch the above three alternate processes on the SAME P vs. V diagram, showing the differences between the three curves as accurately as possible. Make sure to indicate the initial and final points and the direction arrows for each curve.
