Entropy (Class Notes)

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.…
