The compressibility of water is 6×10-10N-1m2. If one litre is subjected to a pressure of 4 x 107 N m-2, the decrease in its volume is

Bulk modulus, B = -P(∆VV)-ve sign shows that with a increase in pressure, a decrease in volume occurs.Compressibility, K = 12 = -∆VPVDecrease in volume, ∆V = PVK= 4 × 107×1×6×10-10= 24 ×10-3 litre= 24 × 10-3 103 cm3 = 24 cc
