Answer:
Coils of electric toasters and electric irons made of an alloy rather than a pure metal due to the following reasons: The resistivity of an alloy is higher than the pure metal. At high temperatures, the alloys do not oxidize. Alloy does not melt readily and get deformed.

Explanation:
Coils of electric toasters and electric irons made of an alloy rather than a pure metal due to the following reasons:
The resistivity of an alloy is higher than the pure metal.
At high temperatures, the alloys do not oxidize.
Alloy does not melt readily and get deformed.
Alloys have a low-temperature coefficient of resistance
Hence, the coils of heating appliances such as electric toasters and electric irons are made of an alloy rather than a pure metal.
