Question

The liquids boil at lower temperature at high altitude because:

• A. Atmospheric pressure is low at high altitudes
• B. Atmospheric pressure is high at high altitude
• C. Viscosity of a liquid decreases at high altitude
• D. Viscosity of a liquid increases at high altitude

Answer 1

The correct option is A

Atmospheric pressure is low at high altitudes

At high altitudes the atmospheric pressure is quite low as compared to that at sea level. So water boils at a lower temperature at high altitudes.
