How the particles of pepper moved as the water became hotter?

As the water heats up, the particles gain energy and move more rapidly, causing increased agitation. This agitation results in the pepper particles being pushed around and dispersed more quickly throughout the water. The warmer water creates currents that help mix the pepper, making it spread out rather than clump together. Consequently, the movement of both the water and the pepper particles enhances the overall distribution of the pepper in the liquid.
