Beautiful Bonds: The World of Covalent and Metallic Solids

Covalent solids, also known as network solids, are materials with atoms bonded together in a continuous network by covalent bonds, resulting in large, rigid structures....

We use a metal box holding rods of different materials to test their ability to conduct heat. The box is filled with boiling water and a paperclip is attached to the end of each rod using petroleum jelly. As the heat moves through the...

This video is answering the question of where can I find insulators and conductors.

Four different materials are shown, but which is the only one that is not an insulator?

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

Dr. Forrester explains the production of electricity and materials used to insulate and conduct it.

This video explains the concept of thermal conduction, which is the transfer of thermal energy through solids. The video discusses the three main mechanisms of thermal energy transfer, thermal conduction, convection and thermal...
