Properties of Matter 1 Question 11

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

(a) 204.8×105Pa

(b) 102.4×105Pa

(c) 51.2×105Pa

(d) 1.55×105Pa

(2005,2M)

Show Answer

Answer:

Correct Answer: 11. (d)

Solution:

  1. From the definition of bulk modulus, B=dp(dV/V)

Substituting the values, we have

B=(1.1651.01)×105(10/100)=1.55×105Pa
