Question

The change in volume of a certain mass of liquid is observed to be \(1/500\) of original volume, when pressure on it is increased by \(50 \text{ kgf/cm}^2\) (or \(5000\text{ kN/m}^2\)). Find the bulk modulus of liquid

• A. \(2.5\times10^4 \text{ kgf/cm}^2\)
• B. \(5.5\times10^4 \text{ kgf/cm}^2\)
• C. \(9.5\times10^4 \text{ kgf/cm}^2\)
• D. \(15.6\times10^4 \text{ kgf/cm}^2\)

Hint:

Bulk modulus is simply the reciprocal of compressibility.
Multiply the change in pressure directly by the inverse of the fractional change:
\[ 50 \cdot 500 = 25000 = 2.5 \times 10^4 \]
