  Several alternative approaches to quantum gravity problem suggest the
modification of the {\it fundamental volume $\omega_{0}$} of the accessible
phase space for representative points. This modified fundamental volume has a
novel momentum dependence. In this paper, we study the effects of this
modification on the thermodynamics of an ideal gas within the microcanonical
ensemble and using the generalized uncertainty principle(GUP). Although the
induced modifications are important only in quantum gravity era, possible
experimental manifestation of these effects may provides strong support for
underlying quantum gravity proposal.
