. 2.3 moles of an ideal gas originally at STP expands irreversibly and isothermally from point A to point B in the Carnot cycle diagram. It then is expanded reversibly and adiabatically from B to C. What is the volume and the pressure at the point
B? pC = 0.288 atm, VC = 143 liter, Cv = 3R/2.
a) What is the volume at point B in liters?
b) What is the entropy change of the fluid?
