Density, Compressibility & Pascal's Law

The bulk modulus of a liquid is 3 ×\times 1010 Nm−2{}^{-2}. The pressure required to reduce the volume of liquid by 2% is:

Show answer and solution

Answer: (c)

  1. B=PΔV/V⇒P=BΔVVB = \dfrac{P}{\Delta V/V} \Rightarrow P = B\dfrac{\Delta V}{V}
  2. P=3×1010×0.02=6×108 N m−2P = 3\times10^{10}\times0.02 = 6\times10^8\text{ N m}^{-2}
  3. So the answer is (c).
