Find the increase in pressure required to decrease the volume of water sample by 0.01 % . Bulk modulus of water =2.1 10^9 Nm ⁻²
Options
- A4.3 10^4 ~N / m ^2
- B1.8 10^7 ~N / m ^2
- C2.1 10^5 ~N / m ^2
- D3.7 10^4 ~N / m ^2
Correct answer
C. 2.1 10^5 ~N / m ^2
Step-by-step solution
As , =2.1 10^9 ~N / m ^2 Also given that V V =0.1 %=10⁻⁴ We know that, B= p V V aligned p & =B ( V V ) & =2.1 10^9 10⁻⁴ & =2.1 10^5 ~N / m ^2 aligned
