Is there a physics equation to explain bubbles in fluids?

If the vapor pressure of a liquid (or dissolved component in the liquid) exceeds atmospheric pressure, it will start escaping from the liquid phase into tiny trapped air pockets located on the surface of the container. The process continues until the bubble grows large enough so the buoyant force can overcome surface tension affects, and the bubble breaks free. The tiny air pocket remains behind to start the process again.

Some gasses will dissolve in some fluids.
For example dissolved oxygen in water is what allows animals with gills etc. to live in that water.
As a graphic example, where I live people get their water from wells. A fellow I know kept buying goldfish for his daughter, and they would always die as soon as he got them home and put them in a bowl of "fresh" water. Poor in dissolved oxygen.
If you have water that has quite a bit of air dissolved in it, and that is done at treatment plants and sometimes by the faucet you get it from, that air will sometimes go back into a gas from a number of potential reasons. If the water warms, it's ability ti hold dissolved air decreases and the air forms bubbles as the air (a mixture of gasses) is "squeezed" out. The bubbles will float to the top. or form on microscopic points on the walls and bottom of the container where they will grow until the are light enough to break free. Try putting some soda pop in a glass, watch where bubbles form. You will notice that as a bubble grows, then floats up, another bubble will form at exactly the same place.

Gases can be dissolved into water, such as CO2 in sodas. This is done at very cold conditions where the solubility is high. As the soda warms, the gas must come back out of solution and forms bubbles, particularly where there are nucleation sites that are favorable to bubble formation.

Bubbles are just gases, gasses are lighter then liquids thus they move up, as for an equation it depends on what gas it is that's making the bubbles.

i do no longer think of people do sink whilst they die interior the water. have you ever accomplished "the lifeless guy's waft" interior the swimming pool, the place you waft interior the water face down? that's what occurs to lifeless people interior the water. the sole reason a individual could sink could be if their outfits or footwear have been weighing them down. they could probable finally end up floating to the outdoors faster or later besides, after their outfits rotted away.

it floats bcoz density of air/gas in bubbles is lighter then water.

becoz bubbles of water are lighter in weight than water,,,,,,,, hence bubbles forms in the water flots off

Because they are filled with gas which is less dense than a liquid, and the gas wants to escape.

water H2O one part hydrogen , two parts oxygen. Ok just guessing but I imagine the separation has something to do with the expansion or contraction of gases during temperature changes?????????????????????????????????????????

floating is due to bouyancy.
It is just part of the bernouli equation, or archimedes principle
