Question

If the compressibility of water is s per unit atmospheric pressure, then the decrease in volume (V) due to atmospheric pressure P will be –

• A. sP/V
• B. sPV
• C. s/PV
• D. sV/P

Answer 1

Answer: (B)

sPV

Answer 2

K = $\frac{P}{\frac{\Delta V}{V}}$ or $\frac{1}{K} = \frac{\Delta V/V}{P}$

or s =$\frac{\Delta V}{PV}$ or DV = sPV.
