An unknown amount of gas is placed in a container with a moveable piston as shown below. The cross-sectional area of the container is A. When a mass M is placed on the piston, the height of the piston above the bottom of the container is h.

An amount of energy Q is transferred by heat to the gas. (Q>0.) Put the magnitudes of the energy Q, work W, and change in internal energy E in order from smallest to largest.

1.Q < W < E
2.Q < E < W
3.W < E < Q
4.W < E = Q
5.W < Q < E
6.E < Q < W
7.E < Q = W
8.E < W < Q
9.None of the above
