  • specific heat capacity
    amount of energy required to raise a 1kg of a substance by 1 degrees at a constant temperature
  • liquid
    all touching
    small gaps
    randomley arranged
    move freely
    weaker forces of attraction
  • SLH of fusion
    solid to liquid
  • solids
    all touching
    no gaps
    neatly arranged
    vibrate at fixed points
    strong forces of attraction
  • SLH of vaporisation
    liquid to gas
  • density
    how compact a substance is
  • specific latent heat
    the amount of energy required to change the state of a 1kg of substance with no temperature change
  • gas
    spread out
    large gaps
    randomley arranged
    weakest forces of attraction
    move freely in a rnage of directiona
  • density = mass /volume
  • internal energy
    the sum of kinetic energy and potential energy of the particls of a substance
