A bubble of air of volume 4.0 mm3 is under water. The bubble is at a depth where the pressure of the air inside the bubble is five times atmospheric pressure.
The temperature of the air in the bubble stays the same as it rises to the surface.
What is the volume of the air in the bubble as it reaches the surface?
