  We use a hadron resonance gas model to calculate the quark-antiquark
condensates for light (up and down) and strange quark flavors at finite
temperatures and chemical potentials. At zero chemical potentials, we find that
at the temperature where the light quark-antiquark condensates entirely vanish
the strange quark-antiquark condensate still keeps a relatively large fraction
of its value in the vacuum. This is in agreement with results obtained in
lattice simulations and in chiral perturbation theory at finite temperature and
zero chemical potentials. Furthermore, we find that this effect slowly
disappears at larger baryon chemical potential. These results might have
significant consequences for our understanding of QCD at finite temperatures
and chemical potentials. Concretely, our results imply that there might be a
domain of temperatures where chiral symmetry is restored for light quarks, but
still broken for strange quark that persists at small chemical potentials. This
might have practical consequences for heavy ion collision experiments.
