Homework 20 question 1. Two moles of an ideal gas are heated at constant pressure from a temperature of 30 ∘C to 104 ∘C.
Calculate the work done by the gas.
1. Determine the maximum possible efficiency for the cycle used in Problem 1 from HW 20, Two moles of an ideal gas are heated at constant pressure from a temperature of 30 ∘C to 104 ∘C. Assuming the same hot and cold temperature (assume there are 2.55 x 1021 molecules of diatomic gas). Compare the actual energy conversion efficiency we calculated for that cycle to the best possible (Carnot) efficiency. 2.Determine the maximum possible efficiency for the cycle used in Problem
2 from HW 20, assuming the same hot and cold temperature (assume there are 5.04 x 1022 molecules of diatomic gas). Compare the actual energy conversion efficiency we calculated for that cycleto the best possible (Carnot) efficiency.

A Carnot cycle is conducted using an ideal diatomic gas. Initially, the gas is at temperature 25C., pressure of 100KPa and volume of 0.01m3. The system is then compressed isothermally to a volume 0.002m3. From that point, the gas undergoes an adiabatic compression ( with gamma= 1.4), until the volume further reduces to 0.001m3. After that, the system goes an isothermal expansion process to a point where the pressure of the system is 263.8KPa. Then the system continues the cycle...
