1.On a pV diagram, draw the path a gas takes as it goes through the following processes: first it undergoes an isochoric heating process, then that’s followed by an isobaric cooling process, finally it goes back to its original position on the pV diagram by undergoing an isothermal expansion.
2. An ideal gas initially at volume V1, pressure P1, and temperature T1 undergoes an isobaric process that changes its temperature to T2. The gas immediately undergoes an isothermal process that changes its volume to V3. What is the final pressure in the gas in terms of these variables?

The working substance in an engine is 3.0 x 1023 He atoms. Initially in state 1, the gas volume is V1=1.5 x 10-3 m3 and the pressure is P1=1.00 x 106 N/m2 . The gas undergoes a cycle that consists of four processes: (1→2) an isothermal expansion, (2→3) an isobaric compression until the volume is V3=2.00 x 10-3 m3 and the pressure is 2.00 x105 N/m2 , (3→4) an isothermal compression until the volume is V4=V1, and (4→1) an isochoric...

An ideal gas with Cv = 5/2R, and γ = 1.4 starts at a volume of 2.0m^3, a pressure of 3.0 × 10^5Pa, and a temperature of 300K. The gas undergoes an isochoric cooling where its pressure decreases to 1.0 × 10^5Pa. It then undergoes an adiabatic contraction until its pressure returns to 3.0×10^5Pa. It finally undergoes an isobaric heating until it returns to a volume of 2.0m^3. What is the efficiency of this heat engine?
