5. The steps of a reversible Stirling engine are as follows. For this problem, we will use 0.001 mol of a monatomic gas that starts at a temperature of 133°C and a volume of 0.1 m3, which will be called point A. Then it goes through the following steps: 1. STEP AB: isothermal expansion at 133o from 0.1 m3 to 0.2 m3 2. STEP BC: isochoric cooling to 33°C 3. STEP CD: isothermal compression at 33°C from 0.2 m3 to...

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...
