15. Ideal gases
15.2. Equation of state

understand that a gas obeying pV ∝ T, where T is the thermodynamic temperature, is known as an ideal gas

15. Ideal gases
15.3. Kinetic theory of gases

explain how molecular movement causes the pressure exerted by a gas and derive and use the relationship pV = ⅓Nm < c² >, where < c² > is the mean-square speed (a simple model considering one-dimensional collisions and then extending to three dimensions using ⅓ < c² > = < cx² > is sufficient)
