What Is Matter

The video explains that everything around us is made of matter, which is defined as any substance with mass and volume. Matter is composed of atoms, which consist of subatomic particles. It exists in different states: solid, liquid, gas, and plasma. Matter can change states through phase transitions like melting, freezing, and sublimation, often involving energy changes. Elements, made of one type of atom, combine to form molecules, leading to complex systems in both living and non-living forms.
