Regarding the solution to a question in the association’s **question set**
Thread Content
Question 4-4 in the association’s question set reads as follows: For the steady-state heat conduction process in multi-layer cylindrical walls with identical thicknesses at each layer, which of the following statements is correct? 1. The material of the layer with the greatest temperature difference has the lowest thermal conductivity； 2. The layer with the greatest temperature difference has the highest thermal resistance ； 3. The amount of heat transferred per unit area in each layer is the same ； 4. The amount of heat transferred per layer is the same. The association’s answer is: 1.2.4. But I think 1 is incorrect. Is there anyone in agreement? Thank you!
The thermal conductivity is inversely proportional to the thermal resistance; since 2 is acceptable, then 1 must be correct
