Matter (Physics)
Matter is anything that has mass and occupies space, existing in three main states - solid, liquid, and gas - each with different properties
Core concept
Solids have a fixed shape and volume, with particles tightly packed together, like ice or a rock.
How it works
Liquids have a fixed volume but take the shape of their container, with particles more loosely packed than solids, like water.
Why it matters
Gases have no fixed shape or volume, filling any container they are in, with particles spread far apart, like air.
Key detail
Matter can change from one state to another through processes like melting, freezing, evaporation, and condensation.
