HVAC Systems Calcs Namely that methanol has a vapour pressure of 1 atm precisely at this temperature - the liquid boils, and pushes back the atmospheric pressure, and bubbles of vapour form directly in the liquid. While it makes sense cooking food above 173 F or78 C would drive off the alcohol and leave the water, scientists at the University of Idaho Department of Agriculturehave measured the amount of alcohol remaining in foods and found most cooking methods don't actually affect the alcohol content as much as you might think. Boiling point is nothing but a point of saturation where the vapour pressure of a solvent equals the atmospheric pressure, simply toluene is a solvent, whose boiling point is 110.6C, and at that boiling point the vapour pressure of toluene will be 760 torr, [Dont get confused Torr means mmHg only]. property for sale ilfracombe.
