Diffusion - Part 3: Hot vs Cold Fluid Densities

Dr. Boyd, a chemist, presents a video on diffusion, focusing on how substances move from high to low concentration. The video includes an experiment using shot glasses, food coloring, and water at different temperatures to demonstrate diffusion. Key concepts such as density and molecular energy are discussed. The experiment shows how hot and cold water interact, leading to mixing and color change, with observations on how temperature affects diffusion.

What materials are needed for the diffusion experiment?

Explain how temperature affects the rate of diffusion in fluids.

Describe the expected outcome when mixing yellow and blue dyed water.

What happens when hot water is placed on top of cold water in the experiment?

What observation can be made after allowing the fluids to stay for a few minutes?
