A scuba diver releases a bubble of air from a depth of 15 metres.
The volume of the bubble at this depth is 15.0 cm3.
The pressure of the gas inside the bubble at this depth is 250 kPa.
The bubble rises to the surface without changing temperature.
Calculate the volume of the bubble when it reaches the surface.
Atmospheric pressure = 100 kPa
