How does the boiling time depend on the amount of water?

WebJul 11, 2024 · Boiling water When you boil water on a stove, the temperature on the bottom of the pot is higher than the boiling point. Steam bubbles are generated, and they help to heat the water at the top of the pot (convection also helps, and conduction of the pot itself). WebSep 11, 2024 · The definition of the boiling point is the temperature at which the vapor pressure equals ambient pressure, at which point particles within the bulk of the liquid begin to vaporize. So if a non volatile solute depresses the vapor pressure, you need a higher temperature to bring the vapor pressure up to ambient, and the boiling point is elevated. biography for 7th graders https://mcelwelldds.com
