MCQ
The atmospheric pressure is sum of the
  • A
    Pressure of the biomolecules
  • Vapour pressure of atmospheric constituents
  • C
    Vapour pressure of chemicals and vapour pressure of volatiles
  • D
    Pressure created on to atmospheric molecules

Answer

Correct option: B.
Vapour pressure of atmospheric constituents
b
The sum of all of Vapour pressure of atmospheric constituents, at sea level, accounts for our atmospheric pressure.

one atmospheric pressure $( atm )=760 \,mm\,Hg$ or $760 \,torrs$.
