The compressibility of a material is
Correct answer: C. The fractional change in volume per unit change in pressure
- A. Product of volume and its pressure
- B. The change in pressure per unit change in volume strain
- C. The fractional change in volume per unit change in pressure
- D. None of the above
Explanation
Compressibility is a measure of how much the volume of a material decreases under pressure. It is defined as the fractional change in volume per unit change in pressure, which is why Option C is correct. Option A confuses compressibility with a thermodynamic property, while Option B describes the bulk modulus, which is the reciprocal of compressibility. Option D is incorrect because a correct definition is provided.
