How Heat Affects Particle Motion

Next Generation Science

This educational video provides a clear, visual explanation of thermal energy and the particle theory of matter. It introduces the concept that all matter is composed of tiny particles in constant motion, demonstrating the direct relationship between particle speed and temperature. Through high-quality animations overlaid on real-world footage, viewers can visualize how particles behave differently in solids, liquids, and gases, and how adding heat energy changes their movement and arrangement.
