Question

a specimen of oil having an initial volume of 5000cm³ is subjected to a pressure of 10⁴N/m² and the volume decreases by 0.20cm³. What is the bulk modulus of the oil ?​

Answer 1

Answer:

 B = 2.5 10⁸ Pa

Explanation:

The volume modulus is defined by

           B = $- \frac{P}{ \frac{\Delta V}{V} }$

           

The negative fate is for the module to be positive since the volume change is negative

       

It is not necessary to reduce the volumes to the SI system, since they are both in the same units

             B = $- \frac{10^4}{ \frac{-0.20}{5000} }$ = $\frac{10^4}{4 \ 10^{-5} }$

             B = 2.5 10⁸ Pa
