We have measured the specific heat, cp, and the Young's moduli, Ea and Eb, in the high-conductivity ab plane of ZrTe3 as functions of temperature. The specific heat is measured using a niobium-doped TaS3 bolometric thermometer, which is described in detail. At its CDW transition (Tc = 65 K), there are pronounced minima (1-2%) in the moduli, but no anomaly in cp (Δcp < 0.05 R = cp/150) is observed, implying that the transition has a strong stress dependence, particularly along a. The lack of a specific-heat anomaly implies that the change in the electronic density of states is less than 2 states/eV.
