The compressibility of water is 4 × 10 - 5 per unit atmospheric pressure. The decrease in volume of 100 c m 3 of water under a pressure of 100 atm will be

Options

  1. A0.4 c m 3
  2. B4 × 10 - 5 c m 3
  3. C0.025 c m 3
  4. D0.004 c m 3

Correct answer

A. 0.4 c m 3

Step-by-step solution

K = 1 B = ∆ V V P . Here, P = 100   a t m , K = 4 × 10 - 5 and V = 100   c m 3 Hence, ∆ V = 0.4   c m 3
