Thermodynamic Processes

    A thermodynamic process is said to occur when the system changes from initial state to final state. The different processes commonly met within the study of chemical thermodynamics are as follows:–

(i).    Isothermal Process:

        When a process is carried out in such a manner that the temperature remains constant throughout the process, it is called Isothermal Process. Obviously, when such a process occurs heat can flow from system to surroundings and vice – versa in order to keep the temperature constant of the system.

(ii).    Adiabatic Process:

        When the process is carried out in such a manner that no heat can flow from system to surrounding or vice – versa i.e. the system is completely insulated from surroundings, it is called an Adiabatic Process.

(iii).    Isochoric Process:

        It is a process during which the volume of system is kept constant.

(iv).    Isobaric Process:

        It is a process during which the pressure of the system is kept constant.
