NEET Physics Question - Thermal Physics

Assertion (A): Liquids usually expand more than solids.

Reason (R): The intermolecular forces in liquids are weaker than in solids.

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

(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(3) (A) is true but (R) is false

(4) Both (A) and (R) are false

Solution:

Assertion (A) is true as liquids typically have higher coefficients of thermal expansion than solids. Reason (R) is true because weaker intermolecular forces in liquids allow molecules to move more freely and separate further upon heating.

(R) correctly explains (A), as the weaker forces enable greater thermal expansion.
