Question

If the coefficient of linear expansion of a solid is 1.2 × 10⁻⁵ ⁰C⁻¹, what is the coefficient of volume expansion of the solid :

Answer 1

Answer:

Option A is correct

Explanation:

Coefficient of given,

Superficial expansion β=20×10

−5

/

0

C

We know that,

6α=3β=2γ

Where α is linear expansion coefficient.

∴6×2×10

−5

=3β

⇒β=2×2×10

−5

=4×10

−5

/

0

C

Hence,

Option A is correct.
