How does the temperature of water affect how fast the food coloring spreads?
In hot water, the food coloring diffuses (spreads out) through the water quickly. 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.
Why does diffusion occur faster in hot water than cold?
Temperature of a substance is related to how fast the molecules are vibrating. Therefore, in the hot water the molecules were vibrating faster than they were in the cold water. This causes the dye in the hot water to actually diffuse, or move throughout the water, more quickly!
In which temperature water did the food coloring spread the slowest?
Food coloring illustrates diffusion in water. Diffusion is the mixing of molecules due to their random motion, whether in a liquid or a gas. Because molecules in cold water have less kinetic energy than in warm water, the diffusion process is much slower than in warm water.
What happens when food coloring is added to water?
When food coloring is added to water, it spreads throughout the water in a process called diffusion. The coloring continues to spread until all parts of the water contain an equal concentration of the dye. Diffusion of the food coloring occurs passively, meaning no outside force is required for it to happen.
