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

Answer: (C)

The fractional change in volume per unit change in

pressure

Answer 2

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