Question
Which of the following units are incorrect?
- 1torr=1mm of Hg
- 1 atm= 273 torr
- 1m3=1000dm3
- 1 Pa=1N/m2
Hint:
One torr is exactly equal to 1/760 atm of pressure.
The correct answer is: 1 atm= 273 torr
- Torr is a synonym of mm of hg. 1 Torr = 0.999999857533699 mmHg
- One torr is exactly equal to 1/760 atm of pressure. The given 1 atm= 273 torr is incorrect.
- 1m3 =1000dm3
- 1 pascal is equal to 1 N/m2.
