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.
