In an isochoric process, what can occur with pressure?

In an isochoric process, which is defined as a process occurring at constant volume, pressure can indeed change in response to changes in temperature. This means that as heat is added to or removed from a system at constant volume, the pressure of the gas within the system will change.

According to the ideal gas law (PV = nRT), if the volume (V) is held constant, any increase in temperature (T) would lead to a corresponding increase in pressure (P), and vice versa. Therefore, the relationship between temperature and pressure under constant volume conditions demonstrates that pressure can change significantly, depending on the thermal energy of the system.

This highlights the key aspect of an isochoric process: while the volume does not change, pressure is not fixed and can vary with temperature adjustments. Thus, the understanding of this thermodynamic principle is essential for grasping how pressure behaves under specific constraints.
