One pound of air undergoes a thermodynamic cycle consisting of three processes: Process 1-2: constant specific volume Process 2-3: constant temperature expansion Process 3-1: constant pressure compression At state 1, the temperature is 540°R and the pressure is 1 atm. At state 2, the pressure is 2 atm. Employing the ideal gas equation of state, determine (a) the temperature at state 2 and (b) specific volume at state 3.
