If the volume of a block of metal changes by

0.12 \%

, when it is heated through

20^{\circ} {C}

, then the coefficient of areal expansion is :

View answer and explanation

Correct option: A

4 \times 10^{-5}{ }^{\circ} {C}^{-1}

Option A (

4 \times 10^{-5}{ }^{\circ} {C}^{-1}

) is correct because the coefficient of areal expansion is two-thirds of the coefficient of volume expansion.
