Abstract
We discuss computer solutions of Newton's equations of motion for unstable systems in a container with time-dependent walls. An expansion leads to the formation of a cluster and a significant increase of the temperature. The question of entropy increase for expansion and compression of the system and the related problem of the feasibility of a perpetum mobile of the second kind are investigated.
