Question

In which of the following conditions can thermal conductivity analyzer be used for multi-component mixtures?

(a) When all the components have same thermal conductivities

(b) When all the components have very different thermal conductivities

(c) When all but one component have same thermal conductivities

(d) When all components have very different thermal conductivities except two of them which are the same

I got this question in semester exam.

I'm obligated to ask this question of Thermal Conductivity Analysers in portion Industrial Gas Analysers of Analytical Instrumentation

Answer 1

The correct choice is (c) When all but one component have same thermal conductivities

The best explanation: When all but one component have the same thermal conductivities, thermal conductivity analyzer can be used for multi-component mixtures. The mixture is then treated as a binary mixture.
