Difference between Isothermal Process and Adiabatic Process
Isothermal and adiabatic processes are two types of thermodynamic processes that describe how a system changes over time.
The main difference is that isothermal processes maintain a constant temperature throughout the process whereas adiabatic processes do not exchange heat with their surroundings.
Before we move to the differences, let’s understand what are Isothermal Process and Adiabatic Process:
- Isothermal Process: An isothermal process is a thermodynamic process that occurs at a constant temperature. During an isothermal process, the system exchanges heat with its surroundings to maintain a constant temperature.
- Adiabatic Process: An adiabatic process, on the other hand, is a thermodynamic process in which no heat is transferred into or out of the system. During an adiabatic process, the system changes its internal energy without any exchange of heat with its surroundings.
Now, let’s move to Isothermal Process vs Adiabatic Process:
Major differences between Isothermal Process and Adiabatic Process
|Isothermal Process||Adiabatic Process|
|Isothermal processes involve heat exchange with the surroundings.||Adiabatic processes do not exchange heat with their surroundings.|
|Isothermal processes occur at a constant temperature.||Adiabatic processes can occur at any temperature.|
|Isothermal processes are generally slower than adiabatic processes because heat exchange takes time.||Adiabatic processes can occur more rapidly.|
|Isothermal processes are often used in refrigeration and air conditioning.||Adiabatic processes are commonly used in engines and turbines.|
|In an isothermal process, the temperature remains constant throughout the process.||In an adiabatic process, the temperature can change.|
Note that sometimes, the question might also be asked as “distinguish between Isothermal Process and Adiabatic Process”.

Isothermal and adiabatic processes are two types of thermodynamic processes that describe how a system changes over time. While both involve changes in temperature, pressure, and volume, they differ in the way heat is transferred into or out of the system.
Understanding the differences between isothermal and adiabatic processes can help individuals to better understand how different systems function and how they can be optimized for different applications.
