text: We study the effects of the ground state entropy of coloured quarks upon the
bag pressure at low temperatures. The vacuum expectation values of the quark and
gluon fields are used to express the interactions in the QCD ground state in the
limit of low temperatures and chemical potentials. Apparently, the inclusion of
this entropy in the equation of state provides the hadron constituents with an
additional heat which causes a decrease in the effective latent heat inside the
hadronic bag and consequently decreases the non-perturbative bag pressure. We
have considered two types of baryonic bags, Delta and Omega(-). In both cases
we have found that the bag pressure decreases with the temperature. On the other
hand, when the coloured quark ground state entropy is not considered, the bag
pressure as conventionally believed remains constant for finite temperature.
