cyclic process
Consider an ideal gas with molar constant volume heat capacity, cV,m = 1.50 R. The gas undergoes the reversible four step cyclic process shown to the left: 1. During step 1, the gas expands isothermally from V1 to V2. 2. During step 2, the gas expands adiabatically from V2 to V3. 3. During step 3, the gas is compressed isothermally from V3 to V4. 4. During step 4, the gas is compressed adiabatically from V4 to V1. Given T1 = 350.0 K, P1 = 1.00 Ã 105 Pa, V1 = 5.82 Ã 10-2 m3 , V2 = 10.0 Ã 10-2 m3 , T3 = 175.0 K,
Perform the following calculations:
a. Determine the pressure, volume, and temperature of the gas at equilibrium points 1, 2, 3, and 4.
