Home » Mechanics » Mechanical Properties of Fluids » Question

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

1. 0.4 cm³
2. 4 × 10^–5 cm³
3. 0.025 cm³
4. 0.004 cm³

Correct Option: A

K =	1	=	(∆V / V)
	B		P

Here, P = 100 atm,
K = 4 × 10^–5 and V = 100 cm³.
Hence, ∆V = 0.4 cm³
