Solids

  • strong forces of attractioon between particles
  • close together
  • fixed positions
  • regular lattice arrangement
  • particles don't move
  • definite shape and volume
  • do not flow
  • vibrate
  • hotter they become, they more the particles vibrate
1 of 4

Liquids

  • weak force of attraction between particles
  • randomly arranged
  • free to move
  • stick closely together
  • definte volume 
  • do not have a definte shape
  • constantly move in random motion
  • hotter they get, faster they move
2 of 4

Gases

  • very weak forces of attraction between particles
  • free to move
  • far apart
  • travel in straight lines
  • do not have definite shape
  • do not have definite volume
  • always fill a container
  • move constantly with random motion
  • hotter it gets, faster it moves
  • expand or pressure increased if heated

Changing State

  • solid is heated
  • particles gain energy
  • vibrate more
  • weakens forces that hold solid togetehr
  • makes solid expand
  • at certain temperatures, particles have enough energy to break free
  • called MELTING
  • solid turns into liquid
  • liquid is heated
  • particles gain more energy
  • particles move fatser
  • weaken and breaks bonds
  • at certain temperatures, particles have enough energy to break their bonds
  • called EVAPORATING
  • liquid turns into gas
