What is the purpose of the U-value when describing the thermal conductivity of a material?

To determine the material's color
To measure the material's hardness
To quantify the material's ability to conduct heat
To assess the material's flexibility

The correct answer is: To quantify the material's ability to conduct heat

The U-value is used to quantify the thermal conductivity of a material, which measures its ability to conduct heat. It is not used to determine the material's color, hardness, or flexibility. The U-value is an important factor in determining the energy efficiency of buildings and choosing appropriate materials for insulation. Therefore, it is important to understand its purpose and use.
