Question

Give reason metals are good conductor of heat

Answer 1

Because they have air tight molecules in the metal which slowly conducts hear from starting end to ending end e.g thermometer Mercury rises from starting to ending

Answer 2

Metals contain several loosely bound valence electrons which can become free easily forming a sea of several electrons called free electrons that can move throughout the metallic conductor. These free electrons allow the easy and fast conduction of heat energy through the metal.
