Thermal expansion of a solid is due to the
(A) symmetric characteristic of the inter atomic potential energy curve of the solid
(B) asymmetric characteristic of the inter atomic potential energy curve of the solid
(C) double well nature of the inter-atomic potential energy curve of the solid
(D) Rotational motion of the atoms of the solid

(C) double well nature of the inter-atomic potential energy curve of the solid
(D) Rotational motion of the atoms of the solid
Correct option (B) asymmetric characteristic of the inter atomic potential energy curve of the solid
Explanation:
Thermal expansion of a solid is due to asymmetric characteristic of inter atomic potential energy curve of the solid.
