Distinguish between isochoric and isobaric processes.

Isochoric and isobaric processes are two types of thermodynamic processes that describe how a system's properties change with respect to pressure, volume, and temperature.

Isochoric Process:

In an isochoric process, the volume of the system remains constant.
Since the volume is constant, no work is done by or on the system (because work in thermodynamics is given by the equation W = PΔV, and ΔV = 0 in an isochoric process).
Heat energy added or removed from the system results in a change in temperature and internal energy of the system.
An example of an isochoric process is heating a gas in a sealed rigid container where the volume cannot change.
Isobaric Process:

In an isobaric process, the pressure of the system remains constant.
As the pressure is constant, any heat added or removed from the system results in a change in the volume of the system.
Work is done in an isobaric process because the volume changes while the pressure remains constant (W = PΔV).
An example of an isobaric process is heating a gas in a piston where the piston moves, keeping the pressure constant.
In summary:

In an isochoric process, volume is constant and no work is done.
In an isobaric process, pressure is constant, and work is done as the volume changes.
