Monsoon said: What are you trying to accomplish or is it just a random question? The boiling point of water is the temperature at which the vapor pressure of the liquid water equals the pressure surrounding the water and the water changes into a vapor. HVAC Systems Calcs Methanol, also known as methyl alcohol, amongst other names, is a chemical and the simplest alcohol, with the formula C H 3 O H (a methyl group linked to a hydroxyl group, often abbreviated MeOH). At normal atmospheric conditions, Ethanol boils at 76 degrees celsius and in vacuum conditions it boils faster at 38 degrees celsius. This means you can obtain very accurate Then we shall continue our discussion further with factors affecting boiling point and how does vacuum affect the boiling point of any substance. Toluene, C6H5-CH3, is a clear colorless liquid, highly flammable with a sweet, pungent aromatic odor. achieve 5 Torrs of vacuum. The higher the pressure, the higher the boiling point, and vice versa. Hence we can say that under vacuum conditions the value of boiling point decreases as the value of ambient pressure reduces. Methanol, CH3-OH, is a colorless, fairly volatile liquid with a faintly sweet pungent odor, similar, but somewhat milder and sweeter than ethanol. calculated and displayed (55.5 kJ/mol).
