These systems are known to be adiabatically isolated systems. According to the first law of thermodynamics,. If we consider a system that is composed of a mixture of gases that act as an adiabatic system when it is expanded, the value of W is positive, and the internal energy is decreased.

But if the system contracts, the value of W is negative, and the internal energy is increased. This indicates that energy in an adiabatic process is transferred to its surroundings only as work.

Some systems with certain chemical reactions can be approximately considered as adiabatic systems because these reactions happen rapidly, not giving it enough time to release energy outside or gain energy from outside. Isentropic: Isentropic means constant entropy. Adiabatic: Adiabatic means constant heat energy. Isentropic: An isentropic process is a process in which entropy of the system remains constant with no irreversibility and heat transfers.

Adiabatic: Adiabatic process is a thermodynamic process that occurs without any heat transfer between a system and its surrounding. Isentropic: Entropy is constant for isentropic processes or systems. Adiabatic: Entropy is not constant for adiabatic processes or systems. Isentropic: For isentropic processes or systems, entropy, equilibrium, and heat energy are constant. Adiabatic: For adiabatic processes or systems, heat energy is constant.

Isentropic: Isentropic processes are reversible. Adiabatic: Adiabatic processes are either reversible or irreversible. The two terms Isentropic and Adiabatic are used to name either thermodynamic processes or systems where those processes take place. The main difference between isentropic and adiabatic is that isentropic means constant entropy whereas adiabatic means constant heat energy.

They are often represented as functions of pressure and volume or temperature and entropy. Adiabatic and Isentropic are two of such processes.

The difference between the terms adiabatic and isentropic lies in the energy transfer mechanism involved and the kind of systems they are consequently. The two terms have varied meanings, however with respect to the field of thermodynamics, they are representative of the external conditions imposed on a particular energy system.

The term adiabatic means that there is no heat transfer i. Therefore, it constitutes a thermally insulated system. It represents an ideal energy transfer process. It may be reversible where the total internal energy remains unchanged or irreversible the total internal energy is altered. In an adiabatic process, the total heat exchanged between the system and its surrounding is zero. As a result, the only variable influencing change in the internal energy of the system is the work done.

Isentropic signifies an idealized adiabatic process — one which is reversible and suffers no change in entropy. Both isentropic processes and adiabatic reversible processes are types of polytropic processes. Adiabatic processes occur in a strictly thermally isolated system whereas isentropic processes may not.
