The word ‘isothermal’ means constant temperature. An isothermal process is a thermodynamic process occurring at a constant temperature.

The word ‘adiabatic’ means isolated from surroundings. Adiabatic process means a process that neither allows the heat to transfer inside nor lets the heat out of the system.

For example, a reaction that takes place in a Dewar Flask is adiabatic. 

In this article, we will discuss adiabatic and isothermal, distinguish between isothermal and adiabatic processes, isobaric isochoric isothermal and adiabatic processes, and understand the process of isothermal adiabatic in detail.
