Note! of 1 Torr. HVAC Systems Calcs So we can say that water also boils at a lower temperature when placed inside vacuum. This should help to obtain Boiling point of a substance is simply that value of surface pressure when the vapour pressure of the liquid becomes equal to the ambient pressure. This affects both the boiling point of water (if you test run it, a thermometer shows 100C in boiling water) and the boiling point of alcohol, for us the azeotrope of 95% alcohol and 5% water. Threads & Torque Calcs Now you can calculate its boiling point under any pressure. To make use of this tool: By clicking on the Advanced mode button, the calculator will display the heat of vaporization of your substance. The boiling point of ethanol is 79*C and under vacuum (28 inHg) it drops to around 34*C. We typically use a rule of an additional op-temp of 50 degrees Celsius above the boiling point of the solvent is enough to boil the solvent and maintain that boil. But if we'd like to be more precise, we should say that water boils at 100C when it's at atmospheric pressure. The oxygen mixed with the blood will disintegrate and lead to a condition called hypoxia or oxygen deprivation.
