Conceptual Physics

P = pressure (force per unit area)

B = bulk modulus (N/m^2 )

V = volume

Pressure units: pascals (Pa = N/m^2 )

The increase in water pressure is

3.2×10^3 Pa. The balloon’s initial

volume was 0.50 m^3. What is it

now?

ǻV = í0.011 m^3

Vf = Vi + ǻV = 0.50 í 0.011 m^3

Vf = 0.49 m^3
