The Bulk modulus for an incompressible liquid is

A
Zero
B
Unity
Correct answer
C
Infinity
D
Between 0 and 1

Solution

The Bulk modulus is given by

B = - \frac{p V}{∆ V}

If liquid is incompressible, so

∆ V = 0

H e n c e, B = - \frac{p V}{0} = \infty ⟹ B = \infty (i n f i n i t y)

Hence, the correct answer is option: 'C'.
