Here’s what we’re covering today:
- Liquids
- Vapourisation
- Vapour pressure
We have already covered state changes & the kinetic model of liquids in O-Levels, so I won’t be touching on that now.
Here we go!

CHEM C1: Relative Atomic Masses
I won’t be covering stoichiometry & mole calculations that were learnt pre-A-Levels.
For now, I’ll jump straight into new info:
- Analysing Mass Spectra
- Calculating Relative Atomic Mass of an Element
Let’s go!
