Question
The normal boiling point is the temperature at which vapor pressure is equal to:
- 1atm
- 2atm
- 3atm
- 4atm
Hint:
V.P.=A.P. liquid starts to boil.
The correct answer is: 1atm
- At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure i.e. 1 atm.
- At standard atmospheric pressure, the liquid particles start to escape the surface, and the liquid boils.
- When the vapor pressure is greater than the atmospheric pressure the liquid will boil at a higher temperature.
- When the vapor pressure is less than the atmospheric pressure the liquid will boil at a lower temperature.
