Physics - Introduction to Matter (Form I)
Muhtasari / Summary: States of matter, changes of state, and density.

Matter is anything that has mass and occupies space. It exists in three states: Solid (definite shape and volume), Liquid (definite volume, no fixed shape), and Gas (neither fixed shape nor volume). Changes of state: Melting (solid→liquid), Freezing (liquid→solid), Evaporation/Boiling (liquid→gas), Condensation (gas→liquid), Sublimation (solid→gas directly). Density = Mass ÷ Volume (kg/m³).
