Adiabatic Process and Its Characteristics

An adiabatic process is a thermodynamic process in which no heat exchange occurs between the system and the surroundings. The word adiabatic means no heat transfer or no exchange of thermal energy. The heat energy is neither lost nor gained from the system, and the temperature of the system changes due to work done on or by the system.

Isentropic Process

An isentropic process is a reversible adiabatic process in which the entropy of the system remains constant. It is a process in which a system undergoes a change without any gain or loss of heat. It is a process that is adiabatic and reversible, and there is no change in the entropy of the system.

Isentropic Process and Its Characteristics

An isentropic process is characterized by the following:

- No heat transfer occurs between the system and the surroundings.
- The process is reversible.
- The entropy of the system remains constant.
- The work done during the process is reversible.
- The change in temperature in the system is due to work done.

Answer

The correct answer is option D, which states that an adiabatic process is an isentropic process for reversible. An adiabatic process is a process in which no heat transfer occurs between the system and the surroundings. An isentropic process is a reversible adiabatic process in which the entropy of the system remains constant. Therefore, an adiabatic process is an isentropic process for reversible. In other words, an adiabatic process can be considered as an isentropic process if it is reversible.
