At high altitudes the boiling point of water decreases because:
Correct answer: A. Atmospheric pressure is low
- A. Atmospheric pressure is low
- B. Temperature is low
- C. Atmospheric pressure is high
- D. None of the above
Explanation
The boiling occurs at lower temperature if atmospheric pressure is lower than 76 cm Hg.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
