उत्तर
Lake has greater pressure at the bottom than the surface as pressure increases with depth. So when the gas bubble is released at the bottom of the lake it experiences more pressure and is small in size but as it rises upwards the pressure experienced by it decreases. So it grows in size as it moves towards the surface from bottom.
