- Solids
- Particle Arrangement: Close together in a regular pattern
- Particle Movement: Vibrate around fixed positions
- Relative energy of particles: Least stored energy
- SC1
- Liquids
- Particle Arrangement: Close together, irregular pattern
- Movement of Particles: Move around each other. Fill shape of container
- Relative energy of particles: Higher than solids, lower than gasses.
- Gases
- Particle Arrangement: Far apart, randomly arranged.
- Particle Movement: Fast in all directions
- Relative energy of particles: Most stored energy
- Stage Changes
- Condensing: Gas to Liquid
- Evaporating/ Boiling: Liquid to Gas
- Freezing: Liquid to Solid
- Deposition: Gas to solid
- Sublimation: Solid to Gas
- Melting: Solid to Liquid
- During a state change:
- Energy is transferred to or from the particles
- Particle arrangement changed
- Particle movement changes
- Melting Points
- Substance begins to freeze if energy is transferred to the surroundings
- Substance begins to melt if energy is transferred to the particles
- State changes are physical changes because the particles themselves are unchanged
- Chemical reactions are chemical changes, changed by rearraning atoms
- Liquids
- Melting Points
- Substance begins to freeze if energy is transferred to the surroundings
- Substance begins to melt if energy is transferred to the particles
- Substance begins to boil if energy is transferred to the particles
- Boiling Point
- Substance begins to condense if energy is transferred to the surroundings

- Liquids
- Boiling Point
- The liquid cools down unless it is heated
- Changing from a liquid to a gas below boiling point
- The remaining particles have less energy
- Particles with high enough energy leave the surface of the liquid
- Changing from a liquid to a gas below boiling point
