Final answer:
Applying heat to a solvent speeds up solute dissolution by increasing molecular movement and collision frequency.
Explanation:
Heating up the solvent gives the molecules more kinetic energy, leading to increased collisions with the solute. This higher energy and frequency of collisions result in a faster dissolution process. The rate of dissolving is also affected by factors like temperature and particle size.
