Metals have high thermal conductivity. Give reason.
Define thermal conductivity. Give its unit.
Explain why on dilution does the conductivity decrease whereas molar conductivity increases for an electrolytic solution.
List down the thermal conductivity of some substances.
Ionic radius increases across the period from left to right .
Assertion (A): Metals have high thermal conductivity. Reason (R): Due to thermal excitation of many electrons from the valence band to the conductance band, metals have high thermal conductivity.
