Explain elasticity using intermolecular forces
Answers
Intermolecular forces exists between molecules. These forces drive the atom back to its original position after the deforming force is removed. But this applies for a elastic material only. The elasticity or the elastic properties of the material or determined by its stress-strain curve.
When a deforming force is applied on a body, the position of the atoms in that body gets displaced, making the material to deform.
Every atom is surrounded by other atoms which have interatomic forces between them. Intermolecular forces exists between molecules. These forces drive the atom back to its original position after the deforming force is removed. But this applies for a elastic material only.
The elasticity or the elastic properties of the material or determined by its stress-strain curve. There is limit upto which material is perfectly elastic, then gradually properties change. After this material becomes plastic in particular region where the deformation is permanent.
These properties are also influenced by the atomic structure and molecular arrangement of the material,how closely the atoms are arranged, or it is a loosely packed structure.
Anyhow, the interatomic forces are responsible for regaining position and size in a elastic material.
