Why does air compressed to a high pressure create heat?

What bounces a ping pong ball back faster, a stationary wall or a mobile wall moving towards the ball? Of course the wall moving towards it since it imparts more energy to the ping pong ball.
That’s kinda like what compression does to the atoms being compressed. The walls squeeze around the atoms to impart extra energy on them. Since heating something up on the atomic scale is bouncing atoms around at higher speed, the extra speed results in higher temperature.
