Path A

A sample of gas in a cylinder of volume 3.96 L at 327 K and 3.28 atm expands to 7.34 L by two different pathways. Path A is an isothermal, reversible expansion. Calculate the work for Path A.

Answer in units of J.

Path B

Path B has two steps. In the first step, the gas is cooled at constant volume (3.96 L) until its pressure drops to 1.77 atm. In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.77 atm until the final volume is 7.34 L.

Calculate the work for Path B.

Answer in units of J.

Help me please ! Do it as detail as you can, if not you can just leave me with the answer... I will try to figure out how you did it !
