Question
1 atm pressure is equal to:
- 760mm of Ag
- 760mm of Hg
- 760mm of Au
- 760mm of Mg
Hint:
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.
