How does the type of material used as an insulator affect heat transfer? Use evidence to support you from the text given.

Answer 1

The type of material used as an insulator affects heat transfer in several ways. First, the conductivity of the material determines how easily heat can pass through it. Materials with low conductivity, such as air, rubber, or ceramics, are effective insulators because they impede the movement of heat. In contrast, materials with high conductivity, like metals, are poor insulators as they allow heat to transfer freely.

The text provides evidence supporting this statement. For example, it states that "materials that are good conductors of heat, such as metals, are not good insulators." This implies that materials with high conductivity do not impede heat transfer and, therefore, are not effective insulation materials.

Furthermore, the text mentions that "air is a poor conductor of heat." This supports the idea that materials with low conductivity, like air, act as good insulators because they inhibit heat transfer.

Another piece of evidence is the comparison between different types of insulating materials. The text mentions that "fiberglass is a very good insulator" and that "wool is also a good insulator." This implies that the specific material used as insulation affects its ability to impede heat transfer.
