O2-Oxygen
Groundwater naturally bubbles to the surface at springs, where water from underground aquifers is forced up to the surface due to pressure differences. Springs can vary in size and flow rate depending on the underlying geology and hydrological conditions.
upwelling
The term that describes the rising of cold water from deeper layers to replace warmer surface water is called upwelling. Upwelling occurs when winds push surface water away from the coastline, allowing cold, nutrient-rich water to rise and replace it.
Water boils at 100 degrees Celsius at standard atmospheric pressure.
Water bubbles up when heated because the heat causes the water molecules to move faster, which decreases their density. As the density of the heated water decreases, it rises to the surface and forms bubbles.
Below the surface
Water vapor (steam) is inside the bubbles that form inside boiling water. The bubbles that form prior to boiling are mostly dissolved gases escaping from the water.
the bubbles in boiling water is water in a gasious state rising to the surface.
When water boils, bubbles of water vapor form and tend to rise to the surface. This is because the vapor is less dense than the surrounding liquid water. As the bubbles rise, they expand due to decreased pressure at the surface, eventually breaking free and releasing steam into the air.
Signs that water is boiling include bubbles rising to the surface rapidly, steam coming off the surface of the water, and the water appearing to be in a constant motion.
The bubbles aren't really "air", but steam. When water reaches 100 degrees centigrade it turns into steam, and it's that steam that create the bubbles you see appearing and rising from the bottom of a pan.
When water boils, bubbles form due to the release of water vapor from the liquid. These bubbles contain water vapor, not air. The water itself does not disappear; it is transformed into water vapor, which you see as bubbles.
The bubbles in boiling water are steam or vaporized water. The bubbles initially do not reach the surface of the billing fluid as the colder water away from the hot bottom cools the steam turning it back to liquid. WHen all the water is at 100oC the bubbles reach the top.
When water boils the gasses which where absorbed are liberated and they expand as a result of the heat causing bubbles which then rise to the surface upon further heating it would be the water turning to steam that expands into bubbles, that is why the bubbles only form at the point of contact with the heat source. there could be some oxygen in the bubbles but it would be extremely small amounts as the heat does not split the bond between the oxygen and the hydrogen.
when it is changing into gas... bubbles. It is boiling when bubbles begin breaking the surface. the water o nthe bottom is being heated it mixes when it rises because of convection currents. after the water is almost 100 C the water that gets hot enough evaporates and comes out as water vapor. The bubbles are full of steam which gets released when the bubble hits the surface.
when any liquid BOILS the bubbles just contain the same substance, but just as a gas.now why did I put 'boils' in capitals?you know if you boil water there are tiny bubbles already forming before it is actually boiling. these are the gasses which were dissolved in the water.
well it depends if you boil it over a fire sometimes bubbles do occur but if your just heating it at a temperature lower than boiling than it just slowly evaporates like regular water in a lake
