Final answer:

Diffusion is a process that is not size-independent, as it is affected by factors like particle size and temperature. Melting, evaporation, and sublimation are size-independent processes.

Step-by-step explanation:

The question asks which of the following processes is NOT size-independent: melting, evaporation, sublimation, or diffusion. The correct answer is diffusion, as it is the movement of particles from a region of higher concentration to a region of lower concentration and is influenced by factors like particle size and temperature. On the other hand, melting, evaporation, and sublimation are phase transitions that are generally considered size-independent, as they can happen regardless of the amount of the substance provided the necessary conditions (such as temperature and pressure) are met.
