Isentropic

Of equal or constant entropy with respect to either space or time.

The entropy of a substance is that thermal property of it which remains constant when the substance neither gains nor loses heat from external sources, as in adiabatic operations, and which is increased or reduced when heat is given to or taken from the gas.

Consequently adiabatic operations are often called isentropic.
