Dye spreads in water via a process called diffusion. Diffusion occurs in fluids (gases or liquids) and it involves particles moving from a high concentration to a low concentration. So in this context the dye is dropped in and spreads from the high concentration (where the dye was dropped in) to the rest of the water as it has a low or nil concentration of the dye in question. This happens until equilibrium where there is an equal concentration throughout the water. That is why it appear to dilute the dye as the final concentration is actually less than that of the original dye as it has spread out. Therefore this effect will be more pronounced in larger bodies of water as it spread through a larger amount of space so it spread out more and therefore less concentrated.

Will carmine powder plus water cause diffusion?
Yes, carmine powder will diffuse in water because it is a water-soluble dye. When carmine powder is added to water, the particles will disperse and spread evenly throughout the water due to diffusion.
Can hot and cold waters mix with food coloring or dye?
Yes, hot and cold water can mix with food coloring or dye to create a range of colors. The temperature of the water does not affect the ability of the coloring or dye to disperse evenly.
When red food dye is dissolving in water how do the molecules move?
The red food dye would fill in the spaces in the molecules thus turning it red. When there are no spaces the the dye would collect in the bottom of the container
Is food dye a physical or chemical change?
Physical, the water is still water and the food coloring is still food coloring you just mixed them together in one space. If you waited long enough the food coloring and water would settle back out so you had just water and food coloring.
What process causes water to change color from food coloring?
This is the diffusion of the coloring agent molecules in water.
