Assertion : Temperature near the sea-coast are moderate.
Reason : Water has a high thermal conductivity.

(A) : Temperatures near the sea coast are moderate. ( R) : Water has a high thermal conductivity.

Metals have high thermal conductivity. Give reason.

Assertion: Water can absorb large amount of heat energy.Reason : Water has a very high specific heat capacity.

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.

A solid with high electrical and thermal conductivity is

Assertion : The connecting wires are made of copper. Reason : The electrical conductivity of copper is high

Assertion:Ether has higher vapour pressure than water at a given temperature. Reason: Water has stronger inter molecular forces than ether.
