We looked at gas kinetic particles. We introduced the particle density and developed the Maxwell-Boltzmann speed distribution. We derived the peak velocity, the mean velocity and the rms velocity.

We covered the collision frequency, mean free path. We have now successfully derived expressions for the gas kinetic parameters, particle density, random velocity, collision frequency and mean free path.

We turned to macroscopic properties of gas. We covered particle flux, momentum flux, pressure and temperature.

We covered the ideal gas equation, the specific heat capacity and the adiabatic changes of state. We have now successfully derived the macroscopic parameters, pressure temperature and specific heat capacity.

We covered the aerostatic equation. and the barometric law.

We looked at the homework assignment and then continued with the course. We covered the barometric law. We looked at an example of the relative decrease of the number density of gas particles in the atmosphere of Mars. The we summarized the atmospheric divisions.
