Bonding, Structure and Properties of Matter
States of Matter
Three States of Matter
Everything is made of matter
Solids
The particles have a regular arrangement
The particles are very close together
The particles vibrate about fixed positions
The 'particle model' describes the three states of matter
The particle model doesn't take into account...
The forces between the particles
The volume of the particles
The space between the particles
Liquids
The particles have a random arrangement
The particles are close together
The particles flow around each other
Gases
The particles have a random arrangement
The particles are much further apart
The particles move very quickly in all directions
Changing states
When a substance changes state...
The actual particles stay the same
The way the particles are arranged changes
The way the particles move changes
A pure substance will...
Melt and freeze at one specific temperature (melting point)
Boil and condense at one specific temperature (boiling point)
