a) An unknown gas is initially at (1, 1). Draw the following quasi-equilibrium processes on a single P-v diagram, starting from state 1:i. Isobaric expansion, tripling the volume.ii. Isochoric heat addition, which doubles the pressure.iii. Isobaric compression, reducing the volume to half its initial value.iv. Isochoric heat removal, causing the pressure to drop to half its initial value.v. Isobaric expansion, bringing the volume back to its initial value.vi. Isochoric heat addition, bringing the system back to its original state.b) Do the combined processes of Part A equate to a thermodynamic cycle? Justify your answer.
