State of Matter

Longitudinal strain: If there is a change in the length of a body due to the applied force, then the strain is called longitudinal strain.…

Strain: The change produced in the dimensions of a body under a system forces or couples in equilibrium is called strain. This strain can be…

Elastic fatigue: It has been found from the experiment that if a successive increase or decrease of stress is applied on a body or a…

Breaking weight and breaking stress A substance behaves as a perfectly elastic body up to its elastic limit. When the applied force exceeds that limit,…

Elastic limit: We know, everybody is deformed or strained when a force is applied on it, but it returns to its original shape and size…

How the intermolecular force and potential energy between two molecules are changed due to the change of distance between them are discussed below. Suppose, interatomic…

Elasticity in the light of intermolecular force When force is applied on a crystalline body, atoms/molecules of the body are displaced from their equilibrium positions.…

Some quantities are especially related to elasticity which is discussed below: (a) Perfectly elastic body: A body that returns to its original shape and size…

We know, when a force is applied to a body its physical change occurs i.e., the body becomes deformed and when the force is withdrawn…

Intermolecular Force in State of Matter Before discussing elasticity we need to know the structure of matter and why elasticity is produced in matter. Normally…
