States of Matter: Exploring Solids, Liquids, and Gases

The video explains that everything around us is made of matter, which consists of atoms. Matter exists in three states: solid, liquid, and gas. Solids have a definite shape, mass, and volume, while liquids have a definite volume but no definite shape, and gases have neither. The video also discusses how matter can change states, using water as an example, transitioning from ice to water to vapor.
