Give a reason why an air bubble increases in volume as it ascends to the surface of the liquid in a boiler.

Davis
As the air bubbles moves higher, the column of air becomes more thinner hence the atmospheric pressure reduces creating a vacant space which forces the the pressure inside the bubble to press outward to balance with the atmospheric pressure. At a certain point the atmospheric pressure is least and the bubble bursts as a result of pressure imbalance.
