NEET2009PhysicsThermal Properties of MatterActual
Assertion : Liquid molecules have greater potential energy at the melting point. Reason: Intermolecular spacing between molecules increases at melting point.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- BIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
