Diffusion Of Food Coloring In Water

Diffusion Of Food Coloring In Water. Check out this cool science experiment video that focuses on the process of diffusion. Students place drops of food coloring in hot and cold water to observe the different rates of diffusion.

The hot water causes the food coloring to diffuse faster. In this experiment the diffusion of food coloring in hot and cold water shows how temperature effects the rate of diffusion. Although one of these refers to chemical properties and the latter social interaction, both are examples or diffusion.

Science: The average kinetic energy of the atoms and/or molecules increases, roughly, in proportion to the absolute temperature: [eq] As the temperature increases, the diffusivity increases.

Description A drop of food coloring is placed gently into a beaker of water.

In hot water, the food coloring diffuses (spreads out) through the water quickly. A drop of food coloring slowly diffuses in a beaker of water until the color is evenly dispersed throughout the solution. Because molecules in cold water have less kinetic energy than in warm water, the diffusion process is much slower than in warm water. the process of diffusion by placing drops of food coloring in water with different temperatures.
