At higher altitude, the boiling point of water is less than 100°C. This is because of:
Correct answer: D. Lower atmospheric pressure
- A. Higher atmospheric pressure
- B. Weak hydrogen bonding
- C. No change in atmospheric pressure
- D. Lower atmospheric pressure
Explanation
Boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure

About Evaporation, Boiling Point and Vapour Pressure
Evaporation is the escape of higher-energy molecules from a liquid surface, while vapour pressure is the pressure exerted by vapour in equilibrium with that liquid. The topic distinguishes evaporation from boiling and relates both to temperature, intermolecular forces, surface area, atmospheric pressure and the boiling point.
