The compressibility of water is 5 10⁻¹⁰ ~m ² / N . Pressure of 15 10⁶ ~Pa is applied on 100 ml volume of water. The change in the volume of water is
Options
- A0.75 ml increase.
- B1.50 ml increase.
- C0.75 ml decrease.
- Dzero.
Correct answer
C. 0.75 ml decrease.
Step-by-step solution
(A) Given, array l = 1 ~K =5 10⁻¹⁰ ~m ² / N P =15 MPa =15 10⁶ ~Pa array Bulk modulus, K =- P _ V where, _ V = volumetric strain array l =- _ V P _ V =- P =-5 10⁻¹⁰ 15 10⁶ _ V =7.5 10⁻³ array The correct option is A.
