Information
Diffusion: Water particles and dye particles are in constant motion due to their random thermal movement. When dye is pipetted into the water, the dye particles gradually spread among the water particles. At higher temperatures, all particles move faster, so mixing occurs more quickly.
Tasks:
- Task 1: Pipette dye into the water and observe how the dye particles spread among the water particles.
- Task 2: Compare diffusion at low and high temperatures.
- Task 3: Explain why temperature affects the rate of mixing.
