plzz answer my question

how much should the pressure on a little of water be changed to compress it by 0.10 percent ​

Answer 1

Volume of water, V = 1 L

It is given that water is to be compressed by 0.10%.

∴ Fractional change, ∆V / V = 0.1 / (100 × 1) = 10-3

Bulk modulus, B = ρ / (∆V/V)

ρ = B × (∆V/V)

Bulk modulus of water, B = 2.2 × 109 Nm-2

ρ = 2.2 × 109 × 10-3 = 2.2 × 106 Nm-2

Therefore, the pressure on water should be 2.2 ×106 Nm–2.
