प्रश्न

Explain elasticity using intermolecular forces.

टिप्पणी लिखिए

उत्तर

Elastic behaviour of solid. In a solid, atoms and molecules are arranged in such a way that each molecule is acted upon by the forces due to the neighbouring molecules. When deforming force is applied to a body so that its length increases, then the molecules of the body go far apart.
