The pressure on a volume of liquidV=1.4m3at the surface is approximately equal to the atmospheric pressurePatm=1.00105N/m2. If this volume of liquid is now placed at a depth where the pressure i sP=2.50107N/m2, what will be the change in volume of the liquid? The bulk modulus of the liquid is 9.01010N/m2. (Include the appropriate sign with your answer.)
