THERMAL CONDUCTIVITY OF GASES

This table gives the thermal conductivity of several gases as a function of  temperature. Unless otherwise noted, the values refer to a pressure of 100 kPa (1 bar). The notation P=O indicates the low pressure limiting value is given. In general, the two values differ less than 1 %. Units are milliwatts per meter kelvin. Substances are listed in the modified Hill order (see Introduction).
