Question

If you double the thickness of a wall built from a homogeneous material, the rate of heat loss for a given temperature difference across the thickness will __________.

Answer 1

Answer:

Become one of two equal parts its original value

Explanation:

Generally, heat flow from a higher temperature region to a lower temperature region. In a homogeneous material, the thickness and the thermal conductivity of the material show thermal resistance. Since homogeneous materials have the same composition of materials, conductivity would be 1/resistance. So when you double the thickness of a wall built from a homogeneous material, the rate of heat loss for a given temperature difference across the thickness will be 1/2 its original value.
