Gas laws: JAMB Physics Past Questions and Answers

What the JAMB syllabus covers in Gas laws

Our summary: How the pressure, volume and temperature of a gas are linked, from Boyle's law to the ideal gas equation.

  • Boyle's law (isothermal process)
  • Charles' law (isobaric process)
  • Pressure law (volumetric process)
  • Absolute zero of temperature
  • General gas equation ($\frac{PV}{T} = \text{constant}$)
  • Ideal gas equation (e.g., $PV = nRT$)
  • Van der Waals gas

Objectives

  • interpret the gas laws;
  • use expression of these laws to solve numerical problems;
  • interpret Van der Waals equation for one mole of a real gas.
