Kinetic Molecular Theory of Gases

Topic Concepts Experiment
Basic Concepts The postulates of the kinetic molecular theory of gases are presented and discussed. A molecular-dynamics simulation of a gas is presented.
Maxwell Distribution The meaning of the Maxwell distribution is discussed. A molecular-dynamics simulation of a gas is employed to explore the effect of temperature on the shape of the Maxwell distribution.
Pressure of a Gas The physical origin of the pressure of a gas is discussed. A molecular-dynamics simulation of a gas is employed to explore the effect of particle mass and number of particles (in a fixed volume) on the pressure of a gas.
Pressure-Volume Relation The relation between pressure and volume for an ideal gas is discussed. A molecular-dynamics simulation of a gas is employed to explore the effect of system volume on the pressure of a gas under isothermal conditions.
Pressure-Temperature Relation The relation between pressure and temperature for an ideal gas is discussed. A molecular-dynamics simulation of a gas is employed to explore the effect of system temperature on the pressure of a gas under isochoric conditions.
Diffusion The concept of diffusion is described and illustrated. A molecular-dynamics simulation of a gas is employed to explore the random-walk motion of a molecule.
