Glass becomes bigger when heated
WebHeat is initially transferred through the glass wall of the beaker by conduction. The water in the region of the Bunsen flame is heated. It expands, becomes less dense and rises. WebWhen the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.
