Detailed explanation-1: -The correct answer is Diffusion. Food coloring dispersing in water is an example of diffusion. Diffusion is the mixing of molecules due to their random motion, whether in a liquid or a gas.

Detailed explanation-2: -In hot water, the food coloring diffuses (spreads out) through the water quickly. 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.

Detailed explanation-3: -Also osmosis is the diffusion of water. For example, when food coloring is put in water, it slowly spreads out, or diffuses. Osmosis is pretty much passive transport, which is the movement of molecules from high to low concentration.

Detailed explanation-4: -Diffusion is the movement of molecules from an area where the molecule is in high concentration to an area where the molecule is in lower concentration. An example would be the food coloring in water.

Detailed explanation-5: -The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.
