An air bubble of volume 20 cm3 is at the bottom of a lake 40 meter deep, where the temperature is 4oC. The bubble rises to the surface, which is at a temperature of 20oC. Take the temperature of the bubble's air to be the same as that of the surrounding water. Just as the bubble reaches the surface, determine what is the volume?
