Subject : 536 Thermodynamics
Keywords : Thermal conductivity;Gas ;Helium
Abstract : This paper describes a method for determining the thermal conductivity of a gas by using a thermal diffusion column and uses it for finding the thermal conductivity of air and helium upto 140 degree centigrade. The study widens the scope for finding the thermal conductivity of a gas at still higher temperatures.
