We have seen that the Carnot cycle can be used to determine the maximum efficiency of a heat engine. The efficiency is defined as the sum of all of the work during the cycle divided by the amount of heat exchanged during the expansion process: efficiency=?1 +?2 +?3 +?3 /?1 Theoretically, the efficiency of the engine can be determined with the hot and cold temperature of the cycle. efficiency = ?h − ?c/ ?h In this problem, we will calculate...

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...

Please solve ONLY question (2) with providing explanations of how you solve it. You will see an example of what I’m asking for in Q4. A Problem 2 (10 points) 15 kg of an ideal gas is contained in a piston-cylinder device at an initial pressure of 500 kPa and specific volume of 0.4 m3/kg. The gas is subsequently expanded to a specific volume of 1.3 m/kg During the expansion process, the pressure drops to 125 kPa and it is...
