Problem P. 4079. (May 2008)

P. 4079. There is a sample of neon in a cylinder which is closed by a piston. The gas is compressed such that its volume decreased to two-thirds of the original volume. The pV graph of the process is a straight line segment. In the final state the pressure of the gas is twice as much as it was originally.

a) By what factor did the absolute temperature of the gas increased?

b) How much thermal energy was absorbed by the gas from its environment?

c) How can this process be realized?
