Abstract: An accurate representation of the thermal conductivity of methane and tetrafluoromethane in the limit of zero density valid for the temperature range 120–1000 K with a highest uncertainty of 4%. Also included is a temperature range of 280–750 K with a highest uncertainty of 5% for methane and tetrafluoromethane respectively. These theoretically based correlations are compared to bodies of data, collected mainly from the transient hot wire technique. This paper also compares its correlation with previous ones, and an improved correlation is presented for the temperature dependence of the zero‐density viscosity of tetrafluoromethane.
