Find out the new pressure at which water will boil. The same result is obtained using either method. Mixtures of different molecules are never ideal, but we can treat them as if they were to simplify our calculations. Saturation Pressure. Vapor In chemistry, vapor pressure is the pressure that is exerted on the walls of a sealed container when a substance in it evaporates (converts to a gas). We can use the Omnicalculator tool Vapor pressure calculator or the Clausius Clapeyron equation as follows: As per the Clausius Clapeyron equation, a lower vapor pressure corresponds to a lower boiling point temperature Note that boiling occurs when water pressure is equal to atmospheric pressure. The unit of pressure doesn't matter as long as it's the same for both initial and final pressure. She has conducted survey work for marine spatial planning projects in the Caribbean and provided research support as a graduate fellow for the Sustainable Fisheries Group.
