Question

What will be the decrease in volume of 100 cm3
of water under pressure of 100 atm if the compressibility of water is 4x10- per unit atmospheric pressure?​

Answer 1

Answer:

The compressibility of water is 4x10 per unit atmospheric pressure. The decrease in volume of 100 cubic centimeter of water under a pressure of 100 atmosphere will be. (a) 0.4 cc.

[Q]__?

Bulk modulus (B)= 1 /compressibility = 1 /k

= 1 /4×10^-5 = 0. 25×10^5 atm

= 0.25 × 10^5 × 1.013 × 10^5 Nm-2

= 2.533 × 10^9 Nm^-2

Volume, V= 100 cm^3 = 10^-4 m^3

Pressure, p = 100 atm

= 100 × 1.013 ×10^5 Nm^-2

= 1.013× 10^7 Nm^-2

UsinG

• 1 /B = k = ∆V /pV

∴ ∆V = PV /B

= [1.013 × 10^7 × 10^-4] /2.533×10^9

Decrease in volume,

∆V = 0.4 × 10^-6 m^3

= 0.4 cm^3
