The module focuses on the structure of matter and how particles behave under different conditions. ) is defined as mass per unit volume. Formula:

Solids are generally the most dense, followed by liquids, then gases.

Particles are far apart and move randomly at high speeds. Changes of State Physical changes (reversible) rather than chemical changes. Mass is conserved during a change of state.
