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. Go Direct ® Temperature Probe, Go Direct ® Gas Pressure Sensor, Go Direct ® pH SensorIn this experiment, we will first be looking at how diffusion occurs in hot and cold homogenous mixtures.
