Entropy: number of ways particles can be arranged (disorder) also a measure of the number of ways quanta of energy can be arranged

Increasing Entropy 

  • more molecules = more ways to split up energy
  • energy levels that are closer together = easier to distribute molecules between levels
  • heavier atoms = Levels closer together
  • more complicated molecules = more atoms, therefore more levels + levels are closer together

Molecules within a substance dont contain the same energy

  • Amount of energy spreads out over many energy levels  
  • Amount of energy can change eg.
