WebJan 30, 2024 · 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. WebWhen water freezes, its molecules lose energy and get stuck in a lattice structure in which they are farther apart from each other than in their liquid state, thus making ice less dense than water. The water molecules' low energy in their solid state prevents them from fulfilling the attraction of the hydrogen bonds and moving close to each other. greenhurst thurstoniaWeb4.
