A gas is in a container with a piston lid and is taken from thermodynamic state, 1, to a new thermo- dynamic state, 2, by several different paths, A, B, and C, in the P-V plane. The internal energy of the gas increases during the process. The work done by the gas is largest for path P A 2 B C 1 V. V 2 V The work done by the pas Is the same for the three paths.
