When placed into water, food coloring will begin to mix with the water. The food coloring will mix the fastest in the hot water because the molecules are moving fast due to their increased thermal energy. These fast-moving molecules are pushing the molecules of food coloring around as they move, causing the food coloring to spread faster.

The thermal properties of foods are important in the design of food storage and refrigeration equipment as well as in the estimation of process times for refrigerating, freezing, heating, or drying of foods. Because the thermal properties of foods are strongly dependent upon chemical composition and temperature, the most viable option is to predict these thermal properties using mathematical models that account for the effects of chemical composition and temperature.
