An isochoric process, also known as an isometric process or a constant volume process, is a thermodynamic process in which the volume of the system is held constant while other variables such as pressure, temperature, and internal energy may change. In an isochoric process, the work done on or by the system is zero, since there is no change in volume.
During an isochoric process, the heat transfer into or out of the system can still cause changes in the temperature and internal energy of the system. This can cause the pressure of the system to change, depending on the nature of the system and the conditions of the process.
Isochoric processes are often used in laboratory experiments or industrial processes where the volume of the system is fixed or constrained, such as in a sealed container. For example, heating a gas in a sealed container at constant volume will cause its pressure to increase due to an increase in the internal energy of the gas.
Isochoric processes are also useful in thermodynamic analysis, as they provide a useful reference point for determining changes in other variables such as pressure, temperature, and entropy.
A thermodynamic process taking place at constant volume is known as the isochoric process. It is also sometimes called as an isometric process or constant-volume process. The term isochoric has been derived from the Greek words “iso” meaning “constant” or “equal” and “choric” meaning “space” or “volume.”
An isochoric process is one for which,
In such a process, the work done is zero (since dW = P dV = 0 when V = constant). Hence from the first law of thermodynamics
dQ = dU (isochoric process)
The total heat supplied or rejected is also equal to the increase or decrease in the internal energy of the system.
