States of Matter and Molecules

The video tutorial introduces the concept of states of matter, explaining that all things exist as solid, liquid, or gas. It uses examples like a cup and smoke to illustrate these states. The tutorial further explores the molecular structure of solids, describing how molecules are tightly packed, which gives solids a definite shape.
