MCQ

A liquid boils when its vapour pressure equals

✓
The atmospheric pressure
B
Pressure of $76.0 \,cm$ column of mercury
C
The critical pressure
D
The dew point of the surroundings

✓

Answer

Correct option: A.

The atmospheric pressure

a
(a) A liquid gets converted into vapor phase when its vapor pressure becomes equal to the atmospheric pressure.

That's why, a liquid boils faster at high altitude than sea level
