Question
Which one of the following statements is FALSE?
Options :
For an ideal gas, the enthalpy is independent of pressure.
For a real gas going through an adiabatic reversible process, the process equation is given by πππΎ = constant, where P is the pressure, V is the volume and πΎ is the ratio of the specific heats of the gas at constant pressure and constant volume.
For an ideal gas undergoing a reversible polytropic process ππ 1.5 = constant, the equation connecting the pressure, volume and temperature of the gas at any point along the process is π / π = ππ/ π , where π is the gas constant and π is the mass of the gas
Any real gas behaves as an ideal gas at sufficiently low pressure or sufficiently high temperature.
Answer :
For a real gas going through an adiabatic reversible process, the process equation is given by πππΎ = constant, where P is the pressure, V is the volume and πΎ is the ratio of the specific heats of the gas at constant pressure and constant volume.
Solution :
The process πππΎ = Cis applicable for an ideal gas going through an adiabatic reversible process.
