Pressure required to increase the density of water by about 1% is ____________________ atmosphere?
Correct answer: C. 200
- A. 10
- B. 50
- C. 200
- D. 1000
Explanation
Using water's bulk modulus of about 2.2 GPa, a 1% density increase requires roughly 22 MPa, or about 217 atmospheres. Therefore, 200 atm is the closest option.
