Correct answer: C. Bulk's modulus
- A. Compressibility
- B. Young's modulus
- C. Bulk's modulus
- D. Shear's modulus
Explanation
The ratio of volumetric strain to volumetric stress is called c. Bulk's modulus.Here's why:Volumetric strain: It represents the relative change in volume of a material due to applied pressure. It is calculated as the change in volume divided by the original volume.Volumetric stress: It represents the pressure applied to a material, which causes a change in its volume.Bulk modulus (B) is defined as the ratio of volumetric stress (ΔP) to the volumetric strain (ΔV/V):B = ΔP / (ΔV/V)Therefore, Bulk's modulus is the material property that relates the relative change in volume to the applied pressure, making it the correct answer among the options.Young's modulus: It measures the stiffness of a material under tensile or compressive stress (along a single axis), not volumetric stress.Shear modulus: It measures the resistance of a material to deformation under shearing forces, not volumetric stress.Compressibility: This is the reciprocal of Bulk's modulus, not the ratio itself.

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.
