Question
The temperature drop through a two layer furnace wall is null. Each layer is of equal area of cross–section. Which of the following action(s) will result in lowering the temperature null of the interface?
- By increasing the thermal conductivity of outer layer
- By increasing the thermal conductivity of inner layer
- By increasing thickness of outer layer
- By increasing thickness of inner layer
The correct answer is: By increasing thickness of inner layer
Rate of heat flow null
Now, we can see that q can be decreased by increasing thermal conductivity of outer layer null and thickness of inner layernull.

The figure shows two thin rods, one made of aluminum null and the other of steel null. Each rod has the same length and the same initial temperature. They are attached at one end to two separate immovable walls. Temperature of both the rods is increased by the same amount, until the gap between the rods vanishes. Where do the rods meet when the gap vanishes?
