When applied stress changes the volume, the change in volume per unit volume is known as:
Correct answer: C. Volumetric strain
- A. Polymetric strain
- B. Crystalline strain
- C. Volumetric strain
- D. Equal strain
Explanation
The change in volume per unit volume is known as volumetric strain. It is a measure of how much the volume of a material changes in response to an applied stress. The volumetric strain is calculated as the change in volume divided by the original volume.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
