Are the air bubbles that form on a straw submerged in liquid formed from oxygen that is already in the water or are they carried into the water by the straw as it is submerged?

The straw gives energy to dissolved gases in the liquid, be those gases oxygen, or whatever. The energy given to the gases causes those gases to come out of solution in the water, and to collect on the surface of the straw.

The air bubbles that form on a straw submerged in liquid are typically from air that was already in the straw when it was submerged. As the straw is inserted into the liquid, the air inside the straw is displaced, forming bubbles as it escapes from the submerged end of the straw.

What is a very light igneous rock containing air bubbles?
Pumice is a very light igneous rock that contains numerous air bubbles. It is formed during volcanic eruptions when frothy lava cools rapidly, trapping gas bubbles within the rock's structure.
Is soap bubbles a compound or a element?
Soap bubbles are not a compound or an element. They are formed from a thin film of liquid (usually water and soap molecules) enclosing a pocket of air.
How is a low island formed?
A low island is typically formed by the buildup of coral reefs or by volcanic activity. Coral atolls are formed by the growth of coral reefs on the rim of submerged volcanic islands. Volcanic low islands are created by the eruption of underwater volcanoes, with the accumulated lava and ash forming the island over time.
How did bubbles form in basalt?
Bubbles in basalt form during volcanic eruptions when dissolved gases in the molten rock are released as the lava cools and solidifies. As the lava rises to the surface, the decrease in pressure allows the gases to escape, creating bubbles in the rock.
What are pockets of gas in a liquid?
Pockets of gas in a liquid are bubbles trapped within the liquid. These gas bubbles can be formed through processes such as agitation, heating, or chemical reactions. The presence of these gas pockets can affect the properties of the liquid, such as its density and visibility.
How were the low islands of micronesia formed?
The low islands of Micronesia were typically formed by coral reefs growing on the submerged slopes of submerged volcanic mountains, which built up over time to create the islands. Additionally, some low islands in Micronesia were formed by the accumulation of sand and sediment carried by ocean currents and deposited on top of submerged volcanic peaks.
What are islands formed by the buildup of coral reefs on submerged volcanoes called?
submerged islands
Why does bubbles formed from soap?
Bubbles are formed from soap when they are mixed with water and there is air. When air is present and water is mixed with soap, bubbles will definitely form.
How water bubbles are formed?
By air
What are vesicles formed by the action of what?
bubbles
How are air bubbles formed in pancakes?
air bubbles in pancakes are formed because the carbon dioxide is less dense then the pancake batter.
How do scientist think protobionts formed?
Biological molecules were trapped in molecular bubbles. Cell like structures formed from molecular bubbles-apexx
Why does the bubbles of a soap has no colour compared to the soap?
The bubbles of a soap has no colour compared to the soap because when the soap mixes with the water it looses its colour and the bubbles formed are colourless.
When electricity is passed through acidified water bubbles are formed this is because water?
When electricity is passed through acidified water, bubbles are formed because the electricity causes the water molecules to split into hydrogen gas and oxygen gas through electrolysis. The hydrogen gas is formed at the cathode and the oxygen gas is formed at the anode, creating bubbles as they escape from the solution.
What gas is formed that could cause bubbles when you mixed flour water sugar and yeast?
Carbon dioxide is the gas formed during fermentation when you mix flour, water, sugar, and yeast. This gas causes the dough to rise and creates bubbles in the mixture.
Why are bubbles formed by the electrodes in an electrophoresis procedure?
Bubbles formed by the electrodes in an electrophoresis procedure are typically due to electrolysis of water. When current passes through the electrodes, water molecules are split into oxygen gas at the anode and hydrogen gas at the cathode, resulting in the formation of bubbles.
Can bubbles form a rainbow in them?
Yes, bubbles can display a rainbow effect due to the way light is reflected and refracted off the surface of the soap film. The thickness of the bubble wall determines which colors are seen, creating a color spectrum similar to a rainbow.
