Detailed explanation-1: -Materials that are poor conductors of heat are called insulators. Such as Air, Pure Water, paper, wood, glass, rubber, Teflon, etc.
Detailed explanation-2: -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.
Detailed explanation-3: -Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors.
Detailed explanation-4: -Liquids and gases have lower intermolecular attractive forces. So, the molecules are far apart. When heat is supplied, the vibrations cannot be transferred(supplied) easily to other molecules, as they are far apart. So, they are bad conductors of heat or, insulators of heat.
