Based on what you know about matter, explain why the food coloring mixes at different rates

If food coloring is put in cups of cold and hot water. The food coloring in the cup of hot water dissolves faster than that put in the cold water.

This happens because the particle in the hot water has greater kinetic energy with which they are moving about as a result of heat that has been added to them. Because of this movement the food coloring added to the water dissolves at a fast rate. The molecules of cold water are moving at a slower rate because they are not heated. This slow movement slow down the rate of distribution of the food coloring particles that was pour inside the water.
