Consider an ideal gas in a box, n equilibrium at temperature T. The particles each have kinetic energy mv2/2 and are spinless point particles. They are at suficiently low density that their quantum statistics are unimportant. The box is made of a thin but impermeable material, and is surrounded by vacuum. (a) Find the normalized velocity distribution for the particles inside the sealed box, Now, suppose that a small hole of area a is made in the box, but where...
