States of Matter
Phase Changes
Solid to Liquid: Melting
Liquid to Solid: Freezing
Liquid to Gas: Vaporization
Gas to Liquid: Condensation
Solid to Gas: Sublimation
Gas to Solid: Deposition
Endothermic: Solid -> Liquid -> Gas
Exothermic: Gas -> Liquid -> Solid
Pressure: Force per unit area (F/A)
Air pressure: What causes it?
The pull of gravity on the air
The higher the altitude the lower the air pressure
Measuring Air Pressure
Barometer - instrument used to measure air pressure
How does pressure affect the state of matter?
The higher the pressure the more likely it will be a solid
Increased pressure pushes the molecules closer together so they form IMF
Doesn’t work if already a liquid or solid
Properties of Matter
Solid
Position of Particles: Close
IMF Strength: Strong
Movement: Vibrate in Place
Liquid
Position of Particles: Close
IMF Strength: Weak
Movement: Slide against each other
Gas
Position of Particles: Far apart
IMF Strength: None
Movement: Collide with Surroundings
Temperature: average kinetic energy of the particles of matter
Lower temperatures – particles are moving slower, more likely to form IMF’s and therefore more solid like
Higher temperatures – particles are moving faster, with no IMF’s, more likely to be a gas
