If two materials are in contact, with the first material having twice the thermal conductivity of the second, what can be deduced about the temperature gradients in the two materials near the interface between them?

Question

Quizplus · Accepted Answer

The temperature gradient is inversely proportional to the thermal conductivity. Therefore, the material with lower thermal conductivity will have a steeper temperature gradient. Since the first material has twice the thermal conductivity of the second, the temperature gradient in the second material will be twice that of the first.
