IB Chemistry HL 1.5.2 Real gases
Students practise explaining when gases behave least ideally by comparing intermolecular forces, polarity, particle volume, pressure, and temperature conditions.
How this is tested
- explain greater deviation by comparing polar NO with non-polar N2
- identify conditions where gases behave most ideally, especially low pressure and high temperature
- state why higher pressure makes real gases less ideal as particle volume or forces matter
