◆Nature of materials .

5.
a ) Iron is better conductor (10.0 × 10-8).
b) Silver is a best conductor ..............

4. The resistivity of an alloy is higher than the pure metal. Moreover, at high temperatures, the alloys do not melt readily. Hence, the coils of heating appliances such as electric toasters and electric irons are made of an alloy rather than a pure metal....
