Vapour Pressure

a solid ball ...

Question

a solid ball 3cm in diameter is submerged to a depth wher pressure is 10^4 kgf m^-2. find the change in volume of the ball,if bulk modulus is 10^6 Nm^-2

Open in App

Solution

Here we primarily need to do some conversions as 1 kgf/m²= 9.806 pascal
10⁶kgf/m²= 9806000 pascal or N/m²

And K = bulk modulus = - change in pressure / change in volume

9806000 = 10⁴(final pressure ) - 0 ( initial pressure ) / change in volume

change in volume = 10000/9806000=0.001019
