How Does Heat Transfer Work in Water Using Food Coloring?

TL;DR

Heat transfer in water can be demonstrated using food coloring in three glasses of different temperatures. The dispersion of the food coloring reveals how molecular motion varies with temperature, with faster movement in hot water and slower in cold. This lab illustrates convection, one of the key methods of energy transfer.
