Unit 3 · Properties of Substances and Mixtures

Chapter 3.3

The Ideal Gas Law, Kinetic Molecular Theory, and Real Gases

A gas has no idea what its molecules are made of; at ordinary pressures a liter of any gas holds the same number of particles. Then squeeze it hard or chill it, and the molecules start to matter.

By the end

  1. 01Apply the ideal gas law and Dalton's law of partial pressures to gases and mixtures
  2. 02Relate kelvin temperature to average kinetic energy and read a Maxwell–Boltzmann curve by shape
  3. 03Explain with a particle picture why pressure, volume, temperature, and amount relate as they do
  4. 04Predict when and why a real gas deviates from ideal behavior
