What Makes a Good Thermal Insulator?

Answer

A material that does not conduct heat well, i.e., has a relatively low thermal conductivity. Plastics, wood, cork, and some fabrics are good thermal insulators. The reason is that they contain weak molecular bonds in disorderly arrangements. Heat is transferred in a material by the vibration of the atoms and molecules.
