WebWhat affects boiling point of water? The surrounding pressures are the greatest determinant of the boiling point of a liquid. The air pressure in an open system is most definitely the atmosphere on earth. For instance, water reaches the standard atmospheric pressure at 100 degrees centigrade. Water can boil at a lower temperature as elevation ...
WebA: Air pressure certainly affects the freezing temperature. The higher the pressure, the lower the freezing temperature. Since it will take water longer to reach the lower temperature, I’d expect that it would freeze more slowly. There are two ways that the higher pressure lowers the freezing temperature. One is direct. hackensack meridian health employee emailWebJan 30, 2024 · The vapor pressure of a liquid lowers the amount of pressure exerted on the liquid by the atmosphere.
