Question

Water boils at a lower temperature than ${100}^o$C on a hill station, because.

• A. Pressure is lower at high altitudes
• B. Temperature is lower at high altitudes
• C. Water vapours are less at high altitudes
• D. There is cloud formation at high altitudes

Answer 1

The correct option is A Pressure is lower at high altitudes

Pressure decreases as we go up due to which boiling point also decreases. So water boils at a lower temperature than ${100}^{\circ C}$ on hill station.
