Conduction happens in . . . | solids, liquids and gases |
Metals are good conductors of heat and electricity because they contain . . . | de-localised electrons (which are free to move throughout the metal) |
Gases and most non-metals are . . . | poor conductors of heat |
Poor conductors such as glass and plastic are called . . . | insulators |
