The Five Types of Phase Change in Matter

The video tutorial introduces the concept of phase change, which is the transition of matter from one state to another. It covers five types of phase changes: melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), and sublimation (solid to gas without passing through the liquid state). Each type is explained with examples, such as ice melting into water, water freezing into ice, water vaporizing into steam, steam condensing into water droplets, and camphor sublimating directly into gas.
