IB Physics HL B.3.3 Ideal gas model Question Bank

Practise IB Physics HL B.3.3 by testing ideal-gas assumptions against molecular volume, collisions, expansion and real-gas behaviour.

Exam points

Analyse collision rates, travel distances and kinetic energy when an ideal gas expands at constant temperature.
Contrast ideal and real gases using molecular size, intermolecular forces, phase change and pV behaviour.

[Maximum number: 1]

An ideal monatomic gas is kept in a container of volume $2.1 \times 10^{-4} \mathrm{~m}^{3}$ , temperature 310 K and pressure $5.3 \times 10^{5} \mathrm{~Pa}$ .
