Think aboutthe definition of boiling point when answering this question.A certain liquid boils at 250oC at room pressure, 1 atmosphere = 760 torr. If we set up the distillation apparatus to distill this liquid, and attach a vacuum pump so the pressure in the apparatus is 10 torr, will the liquid boil at 250oC, at a lower temperature, or at a higher temperature?Explain.

Expert Solution
Step 1

The process of conversion of liquid molecules into vapours is called evaporation .

The pressure exerted by the vapours on the surface of liquid at a given temperature is called valour pressure .

As temperature increases vapour pressure also increases.
