2. Sketch a PV diagram and find the work done by the gas during the following stages.
(a) A gas is expanded from a volume of 1.0 L to 3.0 L at a constant pressure of 3.0 atm.
(b) The gas is then cooled at constant volume until the pressure falls to 2.0 atm.
(c) The gas is then compressed at a constant pressure of 2.0 atm from a volume of 3.0 L to 1.0 L. Note: Be careful of signs.
(d) The gas is heated until its pressure increases from 2.0 atm to 3.0 atm at a constant volume.
(e) Find the net work done during the complete cycle.
Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and specify the other subparts you’d like answered.
