An expression describing the contribution of the 1st kind
phase transition smearing due to impurities to heat capacity of condensed
systems has been derived under a simple model approximation (weak
binary solutions, equilibrium distribution of impurities). The model
proposed has been observed to agree qualitatively with experimental
data for phase transitions in simple molecular crystals (CF4,
CCl4 - crystal-crystal transitions) and in liquid crystals
(L) (MBBA, BMOAB - nematic LC-isotropic liquid transitions).
