Assertion : Liquid molecules have greater potential energy at the melting point. Reason: Intermolecular spacing between molecules increases at melting point.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

C. If assertion is true but reason is false

Step-by-step solution

When a solid changes into a liquid, the work done against the attraction of molecules is stored in the form of potential energy.
