The pressure inside the bubble is nearly constant because the air is not very dense. Outside the bubble the pressure increases with depth because the water is pretty dense. So the outside pressure is greater on the bottom of the bubble than on the top, and that pushes the bubble upward.

The bubbles have to come to the surface of the water since they are a gas and the gas has to rise to the top of the liquid. I hope I helped answer your question.

bubbles contain air inside it
air is lighter than water
so the bubble will float in water until it reached the surface

Bubbles are a gas, and the gas is less dense than the water so they float to the surface. It's similar to a floatation device floating on the surface of water.

bubbles are made of air.since air is lighter than water it it brings the bubbles to the surface.

Because the O molecule is lighter than the H2O molecule is my guess.
