Answer to Question #274679 in Physical Chemistry for Gelo

Question

An ideal gas undergoes a mechanically reversible process (constant pressure, constant temperature

and adiabatic process. The gas entering a T1=650K and P1=10bar decreases its temperature at constant

pressure where V2=2.91x10-3 m3

. Then, it went to isothermal process to decrease its pressure. Finally,

the gas returns to its initial state. Take Cp=𝟕
