The table shows the water boiling temperature at different vacuum pressure. We can calculate the boiling point of any substance at any value of ambient pressure using the Clausius Claypeyron Equation. Hence the high boiling point of mixture is lowered down in this manner. With the aid of a ruler, draw a line from 20 mmHg in the pressure graph (to the right), through 100C in the middle graph ("boiling point corrected to 760 torr", this is 1 atm), and where this line intersects the line to the left ("Observed . In normal conditions, the boiling point of ethanol is around 78 degrees celsius. In vaccum the boiling point of Ethanol reduces because the ambient pressure decreases. If pressure is applied to the liquid, it must become hotter before it can boil.
