Question

Estimate the change in the density of water in ocean at depth of 500m below the surface. The density of water at the surface is $10301\, kg\,m^{-3}$ & the bulk modulus of water is $2.2 \times 10^9Nm^{-2}$

• A. $2.363 \,kg/m^3$
• B. $1.363 \,kg/m^3$
• C. $4.363 \,kg/m^3$
• D. $3.363 \,kg/m^3$

Answer 1

Answer: (A)

$2.363 \,kg/m^3$

Answer 2
