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.
Does cold water flow faster than hot?
Generally, a fluid’s viscosity is inversely proportional with it’s temperature, which is the measure of resistance against deformation. The higher a fluid’s viscosity, the thicker it is. Therefore hot water flows faster than cold.
Why does hot water dissolve things faster than cold water?
