Particle Theory
- States of Matter
- Solid
- Ice
- Strong attractions
- Vibrate around fixed position
- Volume does not change with pressure
- Ice
- Liquid
- Water
- Weaker attractions
- Move around and slide past each other (particle movement)
- Volume does not change with pressure
- Water
- Gas
- Water Vapour
- Weakest attractions
- Particles move freely and fast
- Collide and bounce randomly
- Gas is pushed into a smaller volume with increased pressure
- Collide and bounce randomly
- Water Vapour
- Solid
- Diffusion
- Process by which particles mix and spread throughout gases and liquids
- Different concentrations are evened out
- Explains how smells travel
- The smaller the relative molecular mass, the quicker particles diffuse
- Mr is relative molecular mass
- Mr is relative molecular mass
- Process by which particles mix and spread throughout gases and liquids
- Changing State
- Change state by heating or cooling
- This is a physical process
- No new chemical substance formed
- Solid to Liquid = melting/freezing
- Liquid to Gas = boiling/condensing
- Solid to Gas = Subliming/Reverse subliming
- Change state by heating or cooling
