Interpretation :
The reason for the liquid in the barometer to not pill out needs to be explained.
Concept Introduction :
Mercury level of barometer indicates the atmospheric pressure of a region. Unless the pressure is changed the mercury level doesn’t fluctuate.

Answer to Problem 8E
As pressure of atmosphere is present the liquid in the barometer thus, it doesn’t spill out.
Explanation of Solution
Standard pressure is 1 atm. It is equal to the pressure of 76 cm mercury column.
The atmosphere exerts pressure and to maintain the pressure, mercury level goes up and becomes fixed where it reaches atmospheric pressure. When the pressure of atmosphere increases or decreases then mercury level also increases or decreases respectively.
The liquid in the barometer doesn’t spill out due to atmospheric pressure.
