Changing state

The video tutorial explains the states of matter: solid, liquid, and gas. It describes how matter can change states through heating or cooling. Solids melt into liquids when heated, and liquids evaporate into gases. The process of evaporation can occur even at temperatures below boiling point. Practical examples, such as a snowman melting, are used to illustrate these concepts.
