Question

how diffusion is affected by hot and cold temperatures ?
​

Answer 1

In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster. At higher temperatures, particles move faster. This faster movement allows diffusion to occur more quickly.
