The magnitude of ethalphy changes for reversible adiabatic expansion of a gas from volume V_(1) to V_(2) (in L) is DeltaH_(1) and for irreversible adiabatic expansion for the same expansion is DeltaH_(2) . Then when DeltaU_(1) and DeltaU_(2) are the changes in magnitudes for the internal energy of gas in the two expansions.

The magnitude of ethalphy changes for reversible adiabatic expansion of a gas from volume V_(1) to V_(2) (in L) is DeltaH_(1) and for irreversible adiabatic expansion for the same expansion is DeltaH_(2) . Then when DeltaU_(1) and DeltaU_(2) are the changes in mahnitudes for the internal energy of gas in the two expansions.
