Abstract
The compatibility of possible continuous cosmologic particle creation with thermodynamics is studied. It is found that with the usualK=2 Pfafflan (dQ=TdS) is compatible only in very special cases.K≥3 Pfafflans can easily be reconciled with continuous creation. Since then the full thermodynamic state space is accessible by quasistatic adiabatic processes, such systems show local rather than global irreversibility. This property may prevent Heat Death even with idefinitely old model Universes.
