Q. The Bulk modulus for an incompressible liquid is
A) Zero
B) Unity
C) Infinity
D) Between 0 and 1
Explanation
(c) The Bulk modulus is given by
$B = - \frac{pV}{\mathrm{\Delta}V}$
If liquid is incompressible, so
$\mathrm{\Delta}V = 0$
$Hence,\ \ \ B = - \frac{pV}{0} = \infty \Longrightarrow B = \infty(infinity)$
