  Type I superconductivity has recently been reported for the Dirac semimetal
PdTe$_2$ (Tc approximately 1.6K) with, remarkably, multiple critical fields and
a complex phase diagram. Here, measurements of the specific heat utilizing a
thermal relaxation technique are presented. Conventional weak-coupling BCS
superconductivity is confirmed by examining the temperature dependence of the
specific heat in zero field. By probing the latent heat accompanying the
superconducting transition, thermodynamic evidence for type I superconductivity
is attained. The presence of the intermediate state is observed as a
significant broadening of the superconducting transition onto lower
temperatures at high fields as well as irreversibility in the specific heat in
zero field cooled data at 8.5 mT.
