Should not the collision be elastic at least where the atoms are gaseous...?


...that involves NO LOSS of kinetic energy. And such collisions give rise to the macroscopic phenomenon of pressure.

And such elastic collisions underlie the kinetic-molecular gas theory, which allows for state functions relating temperature, pressure, and volume, for a given quantity of gas..
