Question

The compressibility of a material is

• 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

Answer 1

The correct option is C

The fractional change in volume per unit change in pressure

$\frac{1}{K}=compressibility=\left(\frac{\frac{-△V}{V}}{△P}\right)$
