(a) Probes Gas 2. (12 points, suggested time 25 minutes) A cylinder with a movable piston contains a sample of ideal gas. A temperature probe and a pressure probe are inserted into the cylinder, as shown above. The sample of gas is taken through a three-step cycle, ABCA. In process AB, the volume is decreased to 1/4 its original value while constant pressure is maintained. In process BC, the gas expands back to its original volume isothermally. In process CA, the gas returns to its original state without any work being done on or by the gas. PA -Piston i. On the axes below, draw a graph of pressure P as a function of volume V for the three-step process ABCA, labeling states B and C. The pressure and volume of state A are PA and VA, respectively. Label the axes with the values of pressure and volume for states B and C in terms of P₁ and V₁. P (x 105 Pa) A -V (x 10-³ m³) ii. For process BC, is energy added to the gas by heating or removed from the gas by cooling? Support your claim using physics principles. (a) Probes Gas 2.
