thermodynamics

1. (8 points) Circle all false statements regarding a cyclic process in which 1 mol of an ideal gas changes from state A to state B and back to state A under isothermal conditions: (A) In a reversible expansion to state B followed by a reversible compression back to A, the surroundings are doing work on the system. (B) In a 2-step expansion to state B followed by a 6 step compression back to A, the surroundings are doing work on the system. (C) In a 2-step expansion to state B followed by a 2-step compression back to A, the universe is unchanged. (D) In a reversible expansion to state B followed by a reversible compression back to A, ASuniy = 0. (E) The final volume of the gas will be independent of the path taken
