Abstract
The present contribution deals with thermodynamic aspects of the model of Expansive Nondecelerative Universe. In this model, in the matter era a dependence T^CBR ~ E^CBR ~ a(exp -3/4) holds for the energy of cosmic background radiation, E^CBR and its temperature T^CBR, while the proportionality of the energy density epsilon^CBR to the gauge factor a can be expressed as epsilon^CBR ~ a(exp -3). The given relationships comply with experimental observations of the cosmic background radiation as well as with a surprising finding that the Universe expansion is not decelerated by gravitational forces. It is rationalized that the specific entropy is proportional to a(exp -1/4), i.e. it is gradually decreasing in time.
