What is torricelli vacuum?​

Answer 1

Answer:

A Torricelli vacuum is created when a glass tube is filled with mercury and then upended in a vessel containing a level of mercury. The mercury in the tube falls to a level allowed by atmospheric pressure. The vacuum at the top of the mercury column in the glass tube consists of mercury vapor. Changes to atmospheric pressure can be provided by calibrating marking of the glass tube.
