Ideal gas equation
Ideal gas equation
Formula
PV = nRT
Real World
Engineers designing the pressurised cabin of an Airbus A380 use the ideal gas equation to calculate how gas volume changes with altitude and temperature at cruising height.
Exam Focus
Convert all units before substituting: pressure to Pa, volume to m³, temperature to K — unit errors are the most common source of lost marks.
