Elements of electric toasters and electric irons are made of an alloy rather than a pure metal. Give two reasons to justify the statement.
(N/A) Alloys do not oxidise readily at high temperatures,which makes them more resistant to corrosion.
$(b)$ Alloys have higher electrical resistivity (lower electrical conductivity) than pure metals,which allows them to generate more heat when current passes through them.
