Abstract: We report the continuum values of the pressure, P , energy density,
, entropy density, s, the specific heat, Cv , and the speed of sound, Cs , in
quenched QCD, for 0.9 ≤ T /Tc ≤ 3. This is the first direct estimate of Cs
and Cv below Tc in QCD. We also test the approach to a conformal symmetric
theory at high-temperature. These results are obtained using a new variant of
the operator method for the computation of the equation of state, which gives
positive pressure for all temperatures.
