If you touch the metal sides inside of an oven with a bare hand, you’re in trouble. But hold your hand briefly in the oven air and you’re okay. What does this tell you about the relative conductivities of metal and air?
Metal are good conductors of heat.they conduct heat and electricity well and if the conductor has loose electrons in it.air is a poor conductor of heat even when very hot and even though the temperature of them may be high relatively little heat is conducted.hence this about the relative conductivities of metal and air.
