Describe the particle arrangement of a solid.
• Regular structure
• Particles are vibrating in fixed positions
Particle arrangement of a liquid.
Irregularly arranged with particles moving over each other.
Particle arrangement of a gas.
Large gaps between particles. They are moving quickly in random directions
The State Changes
Freezing, melting, evaporating (boiling), condensing, sublimating
Freezing?
Liquid to solid
Melting
Solid to liquid
What is boiling?
Liquid to gas (at its boiling point)
Evaporating?
Liquid to gas (below its boiling point)
Condensing
Gas to liquid
What is sublimating?
Gas to solid or solid to gas
Which state changes use the latent heat of fusion?
Melting and freezing (state changes between solids and liquids)
Which state changes use the latent heat of vaporisation?
Evaporating and condensing (state changes between liquids and gases)
