- Boiling is a physical change that occurs when a liquid is heated to its boiling point and turns into a vapor1. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid1. Initially, the bubbles in boiling water are air bubbles, but bubbles in water brought to a rolling boil consist of water vapor2. Water vapor has a boiling point of 99.98 °C3.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.
Boiling is the process by which a liquid turns into a vapor when it is heated to its boiling point. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid. Boiling is a physical change and molecules are not chemically altered during the process.
chem.libretexts.org/Bookshelves/Physical_and_Th…Initially, the bubbles in boiling water are air bubbles. Bubbles in water brought to a rolling boil consist of water vapor. If you reboil water, bubbles may not form. This can lead to explosive boiling! Bubbles form in other liquids, too. The first bubbles consist of air, followed by the vapor phase of the solvent.
