Consider a gas of a large number N of molecules, each of mass m, enclosed in a cube of volume V = L . When a gas molecule collides with the wall of the container perpendicular to the x axis and bounces off in the opposite direction with the same speed (an elastic collision), the change in momentum is given by: lazzi examples in one man two guvnorsWebAug 19, 2024 · The global atmospheric chemical transport model has become a key technology for air quality forecast and management.
