It gains the energy from radiation (photons) which collide with it. An expanding
gas is a very good example of an action-reaction relationship, both on the
atomic/molecular level, and on the macro level. It is certainly not reactionless.
Gas does not just expand in one direction, it seeks to expand in all directions.
