Answer 1

Answer:

The coils of heating appliances such as electric toasters and electric irons are made of an alloy rather than a pure metal.

Explanation:

Coils of electric toasters and electric irons made of an alloy rather than a pure metal due to the following reasons:

(1) The resistivity of an alloy is higher than the pure metal.

(2) At high temperatures, the alloys do not oxidize.

(3) Alloy does not melt readily and get deformed.

(4) Alloys have a low-temperature coefficient of resistance
