States Of Matter: Solids Liquids And Gases Explained

The video tutorial introduces the three states of matter: solids, liquids, and gases, using water as a primary example. It explains the characteristics of each state, such as definite shape and volume for solids, definite volume but no definite shape for liquids, and neither definite shape nor volume for gases. The tutorial also covers how water can transition between these states through heating and cooling processes.
