Question

1 atm pressure is equal to:

  1. 760mm of Ag
  2. 760mm of Hg
  3. 760mm of Au
  4. 760mm of Mg

hintHint:

Pressure is measured on a mercury scale.

The correct answer is: 760mm of Hg


    • 1 atm is the standard atmospheric pressure.
    • Pressure is also measured on a mercury(Hg) scale due to its high density.
    • Standard atmospheric pressure is the air pressure at sea level.
    • 1 atm pressure is equal to 760mm of Hg.
