Question Analysis
This question involves applying the relationship between atmospheric pressure, vapor pressure, and boiling point to a real-world scenario. The main focus is on understanding how external pressure affects the boiling condition of a liquid.

Key Concept Explanation
Boiling occurs when the external atmospheric pressure equals the vapor pressure of the liquid.
At lower atmospheric pressures (e.g., high altitudes), the liquid reaches its vapor pressure at a lower temperature, resulting in a lower boiling point.
Conversely, higher atmospheric pressure raises the boiling point.

Step-by-Step Solution
1. Recall the boiling condition: External pressure = Vapor pressure of the liquid.
2. Analyze the scenario: High altitudes = Lower atmospheric pressure.
3. Determine the effect on boiling point: To reach the lower external pressure, the liquid needs less therm...
