-Poor conductor of heat -Poor conductor of electricity -Brittle. Explanation;-Periodic table shows three different groups of elements. The metalloid group separates the metals from the nonmetals. Elements to the left are metals and nonmetals are to the right. The exception is the element hydrogen.
What types of materials are poor conductors of heat?
Poor conductors of heat include materials like wood, plastic, rubber, and air. These materials have molecules that are spaced relatively far apart, making it difficult for heat to transfer through ...
Why is air a poor conductor of heat?
Why is air a poor conductor of heat? It is mainly the very low density of gases that make them bad conductors of heat. In liquids and solids atoms and molecules are densely packed and transfer of energy has much smaller distances to happen. In a gas molecules have to scatter off molecules to exchange energy in larger distances, so the ...

What is a poor conductor of heat?
What is a poor conductor of heat? Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. Materials that are poor conductors of heat are called insulators. Air, which has a conduction coefficient of .
The importance of good and bad conductors of heat
The metals are better conductors because they contain free electrons, the electrons move through the metal easily, They gain the kinetic energy from collisions with hot atoms and pass on the energy when they collide with cold atoms, This transfers the heat more quickly..
