Question

Find the increase in pressure required to decrease the volume of water sample by 0.01%. Bulk modulus of water $=2.1\times {10}^{9}N{m}^{-2}$.

• A. $4.3\times {10}^{4}N/m^2$
• B. $1.8\times {10}^{7}N/m^2$
• C. $2.1\times {10}^{5}N/m^2$
• D. $3.7\times {10}^{4}N/m^2$

Answer 1

The correct option is C $2.1\times {10}^{5}N/m^2$

Increase in pressure $=\frac{\Delta V}{V}B=0.0001\times 2.1\times {10}^{9}N/m^2=2.1\times {10}^{5}N/m^2$
