1. States of Matter & Phase Changes Solid, Liquid, & Gas

2. Solid ( + Heat ) Melting- from solid to liquid Melting Point- temperature when something melts Water’s Melting Point (0 o C) Sublimation- solid directly to gas

3. Liquid ( + Heat ) Vaporization- liquid becomes gas Evaporation- takes place at surface & below boiling pt. Water’s Boiling Pt (100 o C) Boiling Point- temp when something changes from liquid to gas

4. Liquid ( - Heat) Freezing- liquid to solid Freezing Point- temp when liquid changes to solid

5. Gas ( - Heat) Condensation- gas changes into a liquid Ex- Beads of water that form on a glass Deposition- gas directly to solid

9. Solid, Liquid, or Gas 3.) Which state of matter does this picture represent?

10. Identify the state of matter that matches each statement. 4.) Has a definite shape & volume 5.) Completely fills the container 6.) Has a definite volume but no definite shape because it takes on the shape of the container 7.) Particles have a lot of energy & move very fast; there is space between the particles 8.) Particles have enough energy to slide past each other but are still touching 9.) Particles have very little energy & vibrate in fixed positions

11. Heat + Heat Gaining thermal energy Particles move faster & temperature rises - Heat Losing thermal energy Particles move slower & temperature drops

12. Plasma- (Copy Down on Front of Foldable) Definition 4 th state of matter Made up of charged (positively & negatively) particles Ex: Neon lights, lightning, stars
