Question

The size of water bubbles increases on moving to the surface.


(a) Name the law responsible for this.

​

Answer 1

Answer:

Because of Boyle's law; the volume of an ideal gas is inversely proportional to its pressure, if temperature is constant.

But we can't conclude that the volume of the bubble will be four times as great at the top than it will at the bottom, if the bottom of the lake is at four atmospheres, because the temperature of the bottom of the lake will not be the same as at the top.

If the bubble actually travels from the bottom to the top or vice-versa, it's going to lose or gain heat in a way that must be quite hard to measure. So this is going to complicate things a lot.
