- 3 STATES OF MATTER: SOLID, LIQUID, GAS
- Atoms - Lesson 2 - Particles
- STATE SYMBOLS
- SYMBOL EQUATIONS can also include STATE SYMBOLS, tells you what PHYSICAL STATE the reactants and products are in
- (S) SOLID (L) LIQUID (G) GAS (AQ) AQUEOUS (DISSOLVED IN WATER)
- SYMBOL EQUATIONS can also include STATE SYMBOLS, tells you what PHYSICAL STATE the reactants and products are in
- CHANGING STATE
- SOLID TURNS TO LIQUID BY MELTING
- LIQUID TURNS TO GAS BY BOILING
- GAS TURNS TO LIQUID BY CONDENSING
- LIQUID TURNS TO SOLID BY FREEZING
- SOLID TO GAS THE PARTICLES ARE HEATED, GAS TO SOLID THE PARTICLES COOL DOWN.
- CHANGING STATE
- SOLID TURNS TO LIQUID BY MELTING
- LIQUID TURNS TO GAS BY BOILING
- GAS TURNS TO LIQUID BY CONDENSING
- LIQUID TURNS TO SOLID BY FREEZING
- SOLID TO GAS THE PARTICLES ARE HEATED, GAS TO SOLID THE PARTICLES COOL DOWN.
- SOLID TO GAS THE PARTICLES ARE HEATED, GAS TO SOLID THE PARTICLES COOL DOWN.
- LIQUID TURNS TO SOLID BY FREEZING
- GAS TURNS TO LIQUID BY CONDENSING
- LIQUID TURNS TO GAS BY BOILING
- PREDICTING the STATE of a substance
- If temp is BELOW the MELTING POINT of substance, it's solid. If ABOVE the BOILING POINT it's a gas and if IN BETWEEN it's a liquid.

- STATE SYMBOLS
- Which state at a certain temperature depends on how STRONG the forces of attraction are between the particles of a material
- The strength of the force depends on the MATERIAL, tr TEMPERATURE, and the PRESSURE.
- PARTICLE THEORY tells us how each state behaves.
- SOLIDS
- STRONG FORCES of attraction - CLOSE TOGETHER - REGULAR ARRANGEMENT
- DON'T MOVE, DEFINITE SHAPE and VOLUME
- VIBRATE, HOTTER it is the MORE they vibrate, causing them to EXPAND when heated.
- LIQUIDS
- WEAK FORCE of attraction. FREE to MOVE past each other. STICK CLOSELY TOGETHER.
- Definite volume but NO DEFINITE SHAPE, FLOWS.
- RANDOM MOTION, HOTTER it gets the FASTER they move. EXPANDS when heated.
- GASES
- VERY WEAK forces of attraction - FREE to MOVE and are FAR APART. Travel in STRAIGHT LINES.
- DON'T keep a definite SHAPE or VOLUME and always FILLS any container.
- RANDOM MOTION. HOTTER the gas is the FASTER it moves. When heated they either EXPAND or their PRESSURE INCRASES
- DOESN'T tell us how strong the forces are and represents the particles by solid inelastic spheres.
