✦ Synopsis

Thermal conductivity of nitrous oxide is measured by the conductivity column method in the temperature range 50° to 900°C._The presently obtained experimental data suggest that it is necessary to take into account the relaxation of translational-internal energy exchange for nitrous oxide in the temperature range 50' to 900°C for its adequate theoretical interpretation.

We have been engaged in a program of measuring thermal conductivity of gases at high temperatures using conductivity columns [ 1,2]. Two variants of this method have been used simultaneously. In one a single column is used and measurements of the electrical energy required to heat the axial wire to different temperatures in the presence and absence of the gas are taken. The difference of the two energy values gives a very good estimate of the energy conducted through the gas and hence thermal conductivity,
