What caused the air above a pot of boiling water to become warm?
What causes the air above a pot of boiling water to become warm? (a) The air transfers thermal energy to the water vapor.
Why does air come out of boiling water?
The solubility of gases decreases when the temperature is raised, and that is why the dissolved air bubbles go out from the water. Then, as the boiling point of water is reached (100 degrees Celsius or 212 degrees Fahrenheit), water vapor starts to form inside the liquid in the form of bubbles.
Where does boiling air come from?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

What is formation of steam from boiling water called?
Condensation. Whereas evaporation is the transformation of liquid water to gaseous water vapor, condensation is the opposite: it is the transformation of vapor back into liquid water. As we said above, when water evaporates, it expands 1600 times larger in volume to become steam.
Does boiling water release oxygen?
During the boiling process bubbles of water vapour, depleted in oxygen, are produced and it is with these that gas exchange takes place. Dissolved oxygen is entrained in the bubbles and then liberated to the atmosphere at the liquid surface.
What is the air in boiling?
These bubbles are water vapor. When you see water at a "rolling boil," the bubbles are entirely water vapor. Water vapor bubbles start to form on nucleation sites, which are often tiny air bubbles, so as water starts to boil, the bubbles consist of a mixture of air and water vapor.
Why Do Compressed Air Cans Get Cold?
Where does steam come from boiling?
When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. The opposite of evaporation is condensation, which is when water vapor condenses back into tiny droplets of water.
Does boiling water release air?
The solubility of gases decreases when the temperature is raised, and that is why the dissolved air bubbles go out from the water. Then, as the boiling point of water is reached (100 degrees Celsius or 212 degrees Fahrenheit), water vapor starts to form inside the liquid in the form of bubbles.

Are bubbles in boiling water oxygen?
By the time water reaches a full, rolling boil, the bubbles consist entirely of water vapor. Boiling water does not decompose it into its elements, so the bubbles do not contain hydrogen gas or oxygen gas (except from the atmosphere).
Does water release oxygen?
When a potential is applied, the water molecules react on the catalyst, splitting into positively charged hydrogen ions (protons) and oxygen atoms, which form oxygen gas that bubbles out of the system.
