Question

The compressibility of water is 4 x 10^-5 per unit atmospheric pressure. The decrease in volume of 100 cm³ of water under a pressure of 100 atmosphere will be:

(a) 0.4 cm³

(b) 4 x 10^-5 cm³

(c) 0.025 cm³

(d) 0.004 cm³

Answer 1

Correct option is : (a) 0.4 cm³

Compressibility = \(\frac{\Delta V}{PV}\)

4 x 10^-5 = \(\frac{\Delta V}{100\times100}\)

∆V = 0.4 cm³
