Values of thermal conductivity and temperature coefficients for thirty‐five pure organic liquids, in addition to those previously reported, obtained with a previously described apparatus (Part I), are presented. Values of thermal conductivity or temperature coefficients for twenty‐eight of these liquids have not been reported before. The experimentally determined maximum error is ±1.0%. The two methods for predicting the thermal conductivity of liquids previously proposed (Parts I and II) are extended to cover the types of compounds studied in this investigation, in particular ring compounds. The temperature coefficient of thermal conductivity was observed to decrease rapidly, approaching zero as the freezing point is approached. The existence of a transition temperature or region within the liquid state is shown and identified with the onset of molecular rotation.
