does not make any guarantee or representation The narrow shape of the containers used in the second experiment slowed down diffusion because of the container’s effect on Brownian motion (the mechanism behind diffusion).Į provides the Science Fair Project Ideas for informational Particles move faster in warmer water, so the red coloring spread more quickly through the cup. Temperature and the shape of the containers affected the rate of diffusion in both experiments. The narrowest container will likely have demonstrated the slower rate of diffusion because fewer molecules are in contact with each other, meaning fewer collisions of the solvent with the solute. Drop one drop of food coloring in each of container and compare their rate of diffusion.Fill both containers with the same temperature of water.This is because particles vibrate faster and harder when they’re warmer-the hot water molecules struck the food coloring molecules harder and more frequently, scattering them until the cup ended up containing a homogeneous solution. You should have noticed that the red food coloring in the hot water dispersed much more quickly than the blue food coloring in the cold water did.

Watch and wait for color to disperse entirely.

Drop 1-2 drops of red food coloring in the hot cup, and 1-2 drops of blue food coloring in the cold in the cold one.

Fill the second glass cup with cold water.

2 differently shaped clear containers (narrow and wide), preferably about the same size.

2 clear glass cups of the exact same size and shape.

How is diffusion affected by hot and cold temperature, and why does the shape of the container make a difference? Materials Then, we can explore how the shape of a container affects the movement of particles. Using food coloring as our solute, or material to be dissolved, we will watch and observe the rate of diffusion occurring in both hot and cold water solvent. A homogenous mixture is one that is made up of materials that are evenly distributed throughout the mixture.

In this experiment, we will first be looking at how diffusion occurs in hot and cold homogenous mixtures.
