The compressibility of water is 4 10⁻⁵ per unit atmospheric pressure. The decrease in volume of 100 ~cm ³ of water under a pressure of 100 atmosphere will be

Options

  1. A0.4 ~cm ³
  2. B4 10⁻⁵ ~cm ³
  3. C0.025 ~cm ³
  4. D0.004 ~cm ³

Correct answer

A. 0.4 ~cm ³

Step-by-step solution

Compressibility = 1 ~B = V / V P . Here, P =100 ~atm Compressibility =4 10⁻⁵ and V =100 ~cm ³ Hence, V =0.4 ~cm ³
