One mole of an ideal gas with C P = (7/2) R and C V = (5/2) R expands from P 1 = 6 bar and T 1 = 500 K to P 2 = 1 bar by each of the following paths: ( a ) Constant volume ( b ) Constant temperature (...

One mole of an ideal gas withC_P
 = (7/2)R andC_V
 = (5/2)R expands fromP
₁ = 6 bar andT
₁ = 500 K toP
₂ = 1 bar by each of the following paths:

(a) Constant volume

(b) Constant temperature

(c) Adiabatically

Assuming mechanical reversibility, . Sketch each path on a singlePV diagram.
