A sample of gas in a cylinder of volume 4.2 L at 316 K and 2.68 atm expands to 7.21 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 has two steps. In the first step, the gas is cooled at constant volume (4.2 L) until its pressure drops to 1.56 atm. In the sec ond step, the gas is heated and allowed to expand against a constant external pressure of 1.56 atm until the final volume is 7.21 L. Calculate the work for Path B.
