As an AI language model, I don't have access to any specific classroom experiments. However, here are some general experiments that might have been conducted in the classroom:
1. Brownian Motion Experiment: This experiment demonstrates the random and continuous motion of particles. In this experiment, small particles like pollen or smoke are added to water and observed under a microscope, and their constant movement is seen as they collide with each other.
2. Diffusion Experiment: Diffusion is the process by which particles move from a region of high concentration to a region of low concentration. In this experiment, a drop of food coloring is added to a glass of water and the movement of molecules is observed. The food coloring molecules move randomly to progressively lower concentration areas until they are evenly distributed throughout the water.
By observing this particle movement, the particle theory is confirmed. It indicates that particles are in constant motion, and that this motion is responsible for phenomena such as diffusion, dissolving, and collisions. These experiments have helped the scientific world to better understand particle behavior and consequences on macroscopic phenomena.
20. Explain how experiments in class proved the particle theory to be true.
