we know metals conduct heat.
Explanation:-
metals conduct heat by the process of conduction. when we heat a piece of metal metal, atom gains energy and starts vibrating. during vibration they transfer the energy to neighbouring atom and neighbouring atom do the same and pass on to the next atom. In this way transfer of heat energy takes place.
let us studie it by an activity.
materials required are Iron scale, burner, Spirit lamp, candle
Take a iron scale amd clamp it on a stand.
Fix a pin on free end of scale using wax.
Heat the scale away from where yhe pin is clamped.
we observe that on heating the scale near the clamp after sometime the pin falls down. this shows that heat flows to the scale and melts ths wax
