Bubbles are basically due to the dissolved air in the water.so when we boil the water,the air gets hotter & comes up in the form of bubbles.
ans2. Nice answer above, but wrong. Sorry.
Even previously boiled water will have bubbles near the heat source.
The bubbles are a few molecules of water, instantaneously (or nearly so) expanding into steam.
Steam occupies about 1600 times the volume of the original water - the molecule! [In an ambient atmosphere at stp. i.e. your kettle. (stp = standard temperature and pressure)]
So this expansion is very rapid, and according to the "equal reaction" phrase, an equal force is generated on the vessel as is exerted on the water around.
The actual expansion point seems to occur at a minor imperfection on the surface of the boiling vessel. Hence our use of bumping devices added to flasks when we are boiling chemicals - we deliberately supply discontinuities.
The same effect may be seen in a glass of soda or of sparkling wine. The dissolved bubbles will only exolve from a particular point. In this case there is not an explosive expansion.
What else can I help you with?
Will air bubbles reappear if boiled water is reheated?
No, air bubbles will not reappear when boiled water is reheated. Boiling causes the air bubbles to escape from the water, and reheating it will not bring the bubbles back.
Will air bubbles appear if boiled water is reheated?
No, air bubbles will not appear when reheating boiled water. The boiling process releases dissolved gases, so when the water is reheated, there are no air bubbles left to be released. The lack of dissolved gases makes it appear that air bubbles do not form when the water is reheated.
When water is boiled in a pot it bubbles Is this the result of a chemical reaction Explain why or why not?
The bubbling of water when boiled is not the result of a chemical reaction. It is due to the conversion of liquid water to water vapor, which forms bubbles as it rises to the surface. This process is physical in nature, involving the phase change from liquid to gas.
What happens when water is boiled over a Bunsen burner?
When water is boiled over a Bunsen burner, the heat from the flame causes the water molecules to gain energy and move faster. This increased kinetic energy causes the water to reach its boiling point, where it changes from a liquid to a gas (vapor). The bubbles you see are the water vapor escaping from the liquid as it boils.
Why does boiled liver react with Hydrogen Peroxide?
Boiled liver reacts with hydrogen peroxide because liver contains enzymes called catalase, which catalyze the breakdown of hydrogen peroxide into oxygen gas and water. This reaction produces bubbles of oxygen gas, which is visible as a foamy reaction when hydrogen peroxide is added to boiled liver.
Will air bubbles reappear if boiled water is reheated?
No, air bubbles will not reappear when boiled water is reheated. Boiling causes the air bubbles to escape from the water, and reheating it will not bring the bubbles back.
What kind of water does not have air bubbles?
Boiled Water.
What is in the bubbles that you see when water is boiling?
If there are big bubbles that pop then it is boiled
Will air bubbles appear if boiled water is reheated?
No, air bubbles will not appear when reheating boiled water. The boiling process releases dissolved gases, so when the water is reheated, there are no air bubbles left to be released. The lack of dissolved gases makes it appear that air bubbles do not form when the water is reheated.
If water is boiled will it turn into water vapor or steam?
When you boil water, a lot of air-bubbles appears on the surface. it is the water turning into steam.
Why does bubbles ran away from each other when water is boiled?
Because they don't like each other. This is currently on unfriendable.com
How do you get bubbles out of ice cubes?
To get bubbles out of ice cubes, try using boiled or distilled water to make the ice cubes. This removes impurities that could cause bubbles. Another method is to let the water sit for a few minutes before freezing, allowing any bubbles to rise to the surface and pop.
When water is boiled in a pot it bubbles Is this the result of a chemical reaction Explain why or why not?
The bubbling of water when boiled is not the result of a chemical reaction. It is due to the conversion of liquid water to water vapor, which forms bubbles as it rises to the surface. This process is physical in nature, involving the phase change from liquid to gas.
Is boiled water distilled water?
No, boiled water is simply boiled. Distilled water is when the steam from the boiling is gathered and rebottled.
When water is boiled the water changes from?
When water is boiled it changes from liquid to a gas.
Which dissolves faster salt or water in boiled water?
Boiled water.
What happens when water is boiled over a Bunsen burner?
