The pressure of a medium is changed from 1.01 × 105 Pa to 1.165 × 105 Pa and change in volume is 10% keeping temperature constant. The Bulk modulus of the medium is

A

204.8 × 105 Pa

B

102.4 × 105 Pa

C

51.2 × 105 Pa

D

1.55 × 105 Pa

Answer

1.55 × 105 Pa

Explanation

Solution

K=ΔpΔV/VK = \frac { \Delta p } { \Delta V / V } =(1.165−1.01)×10510/100=0.155×1051/10= \frac { ( 1.165 - 1.01 ) \times 10 ^ { 5 } } { 10 / 100 } = \frac { 0.155 \times 10 ^ { 5 } } { 1 / 10 }
