Exam points

  • Calculate work done by or on a gas during a constant-pressure change using W = PΔV, with the pressure and volume units converted consistently.
  • Determine work from the area under a pressure–volume graph or the signed area enclosed by a cycle, including estimating areas from grid squares.
  • Use the direction of expansion or compression and the relative areas under the paths to identify whether work is done by or on the gas and determine net work over a cycle.
