Examples
- The isochore on the pressure-temperature diagram shows the behavior of a gas at constant volume.
- In thermodynamics, an isochore represents a process where the volume of a system remains unchanged.
- The meteorologist plotted isochores to identify regions of equal air volume in the atmosphere.
- An isochore process is also called an isovolumetric or constant-volume process.
