Question

Assertion (A) : Alloys are commonly used in electrical heating devices
like electric iron and heater.
Reason (R) : Resistivity of an alloy is generally higher than that of its
constituent metals but the alloys have low melting points then their
constituent metals.
Options
(a) Both A and R are true and R is correct explanation of the assertion.
(b) Both A and R are true but R is not the correct explanation of the assertion.
(c) A is true but R is false.
(d) A is false but R is true
Option B is correct for it or Option A

Answer 1

(a) Both A and R are true and R is correct explanation of the A

Since the alloys are made up of weak bonds, their melting point is lower than their constituents.

Also, alloys are used in the heating devices due to their high resistance which produces more heat energy.
