How is the U-value of a material affected by its thermal conductivity?

  1. Higher thermal conductivity leads to a higher U-value

  2. Higher thermal conductivity leads to a lower U-value

  3. Thermal conductivity does not affect U-value

  4. U-value is inversely proportional to thermal conductivity

The correct answer is: Higher thermal conductivity leads to a higher U-value

The U-value of a material is a measure of its ability to conduct heat, where a lower U-value indicates better insulating properties. When the thermal conductivity of a material is higher, it means that the material is better at conducting heat. Therefore, a material with higher thermal conductivity will have a higher U-value because it is less effective at insulating against heat transfer. So, the correct answer is that higher thermal conductivity leads to a higher U-value.
