A steam pipe is covered with two layers of insulating materials, with ...
k1 < k2 [k1 better insulator]
Q ∝ k. This means that the material having better insulating materia! should be inside to minimize the heat flux hence if better insulating materia! is placed inside, it will reduce the heat transfer.

Explanation:
When a steam pipe is covered with two layers of insulating materials, with the better insulating material forming the outer part, the heat conducted will decrease. This can be explained in the following points:
1. Better insulating material outside:
The better insulating material forms the outer layer, which means that it is the first layer that comes in contact with the surroundings. This layer is responsible for reducing the heat transfer from the pipe to the surroundings. As the better insulating material has a higher thermal resistance, it will reduce the heat transfer more effectively than the inner layer.
2. Inner layer:
The inner layer of insulating material is in contact with the steam pipe. Its main function is to reduce the heat transfer from the pipe to the outer layer. As the outer layer is the better insulating material, it will reduce the heat transfer more effectively than the inner layer.
3. Interchanging the layers:
If the two layers are interchanged, the heat conducted will decrease. This is because, in this case, the better insulating material will be in contact with the steam pipe, which means that it will reduce the heat transfer from the pipe to the surroundings more effectively. This will result in a decrease in the heat conducted.
4. Thickness of each layer:
The thickness of each layer can affect the heat conducted. If the thickness of the inner layer is increased, it will reduce the heat transfer from the pipe to the outer layer. However, this will not affect the overall reduction in heat conducted due to the better insulating material being outside.
Therefore, the correct answer is option 'A', which states that the heat conducted will decrease when the two layers of insulating materials are interchanged.
When a steam pipe is covered with two layers of insulating materials, with the better insulating material forming the outer part, the heat conducted will decrease. This can be explained in the following points:
1. Better insulating material outside:
The better insulating material forms the outer layer, which means that it is the first layer that comes in contact with the surroundings. This layer is responsible for reducing the heat transfer from the pipe to the surroundings. As the better insulating material has a higher thermal resistance, it will reduce the heat transfer more effectively than the inner layer.
2. Inner layer:
The inner layer of insulating material is in contact with the steam pipe. Its main function is to reduce the heat transfer from the pipe to the outer layer. As the outer layer is the better insulating material, it will reduce the heat transfer more effectively than the inner layer.
3. Interchanging the layers:
If the two layers are interchanged, the heat conducted will decrease. This is because, in this case, the better insulating material will be in contact with the steam pipe, which means that it will reduce the heat transfer from the pipe to the surroundings more effectively. This will result in a decrease in the heat conducted.
4. Thickness of each layer:
The thickness of each layer can affect the heat conducted. If the thickness of the inner layer is increased, it will reduce the heat transfer from the pipe to the outer layer. However, this will not affect the overall reduction in heat conducted due to the better insulating material being outside.
Therefore, the correct answer is option 'A', which states that the heat conducted will decrease when the two layers of insulating materials are interchanged.
