Below, figures and tables show the boiling point of water at varying vacuum. At ambient pressure at room conditions the boiling point of water is arpund 100 degrees celsius but when we boil the water in vacuum conditions, it takes only 15 degrees celsius of temperature to boil the water This drop in boiling point is the direct result of reduction in the ambient pressure. Elevation above sea level and the boiling point of water. Reproduction of any materials from the site is strictly forbidden without permission. Now you can calculate its boiling point under any pressure. You know at least two boiling points under two different pressure Then we shall continue our discussion further with factors affecting boiling point and how does vacuum affect the boiling point of any substance. In this article we shall study about the definition of boiling point. Hardware, Metric, ISO The vapors are slightly heavier than air and may explode if ignited. If you do not know the heat of evaporation, press the CHOOSE button and try to This is because of the fact that ambient pressure reduces.
