IDID

The occurence of IDID is probabilistic,that means the compound's boiling point is not fixed:smile_41::smile_41:

IDID being? :smile_41:

認真問的

boiling point係唔係唔fixed:smile_41: :smile_41:

As you said, the IDID is probabilistic. It means that to consider its overall effect on the boiling point of a molecular liquid, we need to apply statistics and concern only the average IDID interaction.

Indeed that is a good question. I have never thought about that before. :smile_44:

polystyrene and expanded polystyrene

佢地既structure有乜唔同?.?

我本CHEM書略略咁講下:smile_27: :smile_27:
