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
Convection normally only happens in . . . liquids and gases (which are able to flow)
The flow of a fluid due to convection is called a . . . convection current
