Question

activities to show diffusion of gases into another liquid

Answer 1

FOOD COLORING IN WATER

Food coloring added to a glass or jar of water will diffuse through water until all of the water is colored. Pour water into a jar and let it sit until all movement of the water has stopped. Add the food coloring one drop at a time so you can see the drop of color slowly spread out throughout the water. Do the same experiment with one jar of hot water and one jar of cold water to see the effect of temperature on diffusion. If the water is still moving, another form of mixing called convection will carry the food coloring around the jar much faster than diffusion.
