An ideal gas undergoes the following Carnot Cycle. It starts in a chamber of volume .0065 m3 and temperature 345 Kelvin and pressure 630 kPa (state 1). It is allowed to expand isothermally to a volume of .01066 m3 (state 2) while heat is added to the gas. Then it expands adiabatically to a volume of .01784 m3 (state 3). Then, it is compressed isothermally to a volume of Vf m3 (state 4) while heat is extracted from the gas. Finally, it returns to its initial state in an adiabatic process. (The gamma of the gas, γ = 1.28, Cv = 3.5R).
What is the change in entropy from state 1 to 2, and 2 to 3?
