What is the Difference Between Isobaric and Isochoric Process?
🆚 Go to Comparative Table 🆚The main difference between isobaric and isochoric processes lies in the factors that remain constant during the process. Both processes are thermodynamic, but they involve different constraints:
- Isobaric Process: In an isobaric process, the pressure of the system remains constant, while the volume and temperature change. This process occurs under constant pressure, and the system keeps the pressure constant by allowing the volume to change, either through expansion or contraction. The internal energy (U) typically changes in an isobaric process.
- Isochoric Process: In an isochoric process, the volume of the system remains constant, while the pressure and temperature change. This process takes place under constant volume, and the system maintains a constant volume while allowing pressure and temperature to change.
In summary:
- An isobaric process occurs at constant pressure, with changes in volume and temperature.
- An isochoric process occurs at constant volume, with changes in pressure and temperature.

Comparative Table: Isobaric vs Isochoric Process
Here is a table comparing the differences between isobaric and isochoric processes:
Process | Definition | Work Done | Pressure | Volume | Temperature | Applications |
---|---|---|---|---|---|---|
Isobaric | A process in which pressure remains constant while allowing changes in volume and temperature. | W = P∆V, where W is work done, P is pressure, and ∆V is change in volume | Held constant | Allows changes | Allows changes | Examples include boiling water and the expansion of a gas in a conducting cylinder |
Isochoric | A process in which volume is held constant, meaning no mechanical work is performed (W = 0). | Zero | Allows changes, may change depending on temperature changes | Held constant | Not applicable (constant temperature) | Calorimetry, bomb calorimeters, and acoustics |
In summary, isobaric processes keep the pressure constant while allowing changes in volume and temperature, and work done is calculated as W = P∆V. On the other hand, isochoric processes have a constant volume, meaning no mechanical work is performed, and pressure may change depending on temperature changes.
