Answer:
Isothermal compressibility is different from isentropic compressibility by temperature instead of entropy.
Explanation:
Isothermal compressibility refers to that type of compressibility where volume change takes place at constant temperature whereas isentropic compressibility refers to that in which volume change takes place at constant entropy. Entropy is the measure of a thermal energy of the system per unit temperature that is unavailable for doing useful work.
