When gas bubbles pass through lime water when first heated, it is likely because the gas being released is carbon dioxide. When carbonates are heated, they decompose to release carbon dioxide gas, which can then react with lime water (aqueous calcium hydroxide) to form a white precipitate of calcium carbonate.

Why will there be air bubbles forming when water is being heated?
Air bubbles form when water is heated because the solubility of gases, like oxygen, decreases as the water temperature rises. As the water heats up, it releases dissolved air in the form of bubbles. Additionally, the bubbles can also come from impurities in the water or gases produced by chemical reactions occurring during heating.
How do bubbles form in boiling water?
Bubbles form in boiling water when the liquid reaches its boiling point, causing the water molecules to gain enough energy to break free from the liquid and turn into vapor. As the vapor rises to the surface, it forms bubbles. These bubbles then burst or rise to the top, releasing the vapor into the air.
How do you prove air is in water?
One way to prove that air is in water is to observe the formation of bubbles when water is agitated or heated. These bubbles are composed of air that was dissolved in the water. Another method is to measure the oxygen or nitrogen content in water, which indicates the presence of air.
Why do vapor bubbles rise to surface when a liquid is boiling?
Vapor bubbles rise to the surface during boiling because the liquid is being heated, causing the molecules to gain energy and form gas bubbles. These bubbles are lighter than the surrounding liquid and therefore float to the surface. The bubbles burst at the surface, releasing the gas into the air.
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 happens to water when it is heated to its boiling point?
It bubbles up dummy.
What does hot water do when it is heated so much that it produces bubbles of steam?
Then it is boiling
Why does water bubble up?
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.

Is there evidence of a chemical reaction when bubbles form on heated water?
Bubbles forming on heated water are usually due to the process of water vaporization rather than a chemical reaction. When water is heated, the molecules gain energy and move faster, eventually reaching a point where they break free from the liquid surface and form bubbles of water vapor. This phase change is a physical process, not a chemical reaction.
Why air bubbles are observed in the water when the round-bottomed flask is heated?
Air bubbles are observed in the water when a round-bottomed flask is heated because heating causes the water to evaporate, forming bubbles of water vapor. These bubbles rise to the surface and escape into the air, creating the appearance of air bubbles when, in fact, they are water vapor bubbles.
What are the bubbles seen in boiling water?
They are regions (bubbles) of gaseous water (water vapor) that have been heated from liquid to gaseous state (having reached the boiling point at 100 deg Celsius).
Why does boiling water spit?
Properties in the water heat and have to expand and it makes bubbles to get air.The water molecules get heated and as they get heated, they begin to move faster and faster.once the water reaches a certain temp it turns to a gaseous form
When water in a beaker is heated bubbles come out to the surface why?
When a droper is dipped into water and its bulb is pressed air bubbles seems to occur in water because the dropper was filled with air before it was dipped in water and when we press the bulb air comes out forming air bubbles and the space is filled with water .
Does tap water make big bubbles?
Without detergent it does not. If you add something like washing up liquid to heated water you can get good bubbles (too watery and they won't have the strength to grow well)
