Figure 3 is a cubical box of edge length L containing n moles of an ideal gas with N molecules moving in all directions. A molecule of mass m and velocity v is about to collide with the shaded wall of area L2. Show that the pressure of the gas in the box is given by: p=nM(v2)avg3V where the terms have their usual meanings.
