Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single mate... More » Science Physics Thermodynamics

In general, metals make good electrical conductors while nonmetallic solids are good insulators, or materials that don't conduct electricity well. Electrolyte solutions, such as salt water, are also good conductors of el... More » Science Physics Electricity

Air is not a good conductor of heat, as it actually serves as an insulator when it is contained in an enclosed area. Air helps to prevent heat loss, instead of transferring heat to or between surfaces. More » Science Earth Science
