Final answer:
An isochoric process involves constant volume, and the question makes sense in that context as it pertains to such processes where volume does not change. No work is done in an isochoric process, and there is no necessity for the process to be slow to maintain volume, unlike the need for slowness in isothermal processes to ensure constant temperature.
Step-by-step explanation:
The question regarding whether the previous question would make sense for an isochoric process can be answered with option (a) because isochoric processes involve constant volume. In thermodynamics, an isochoric process is one where the volume of the system does not change, while pressure may vary. No work is done on or by the system during an isochoric process because work is defined as the product of pressure and change in volume (W = PΔV), and in this case, ΔV = 0.
It is also noted that an isothermal process must be slow to ensure the temperature of the system remains constant as heat is exchanged. This necessity for slowness applies to isobaric (constant pressure) and isochoric processes to maintain thermal equilibrium. However, the pacing of the process is not as critical for isochoric processes because no work is done due to the constant volume.
