In Manila, which is at sea level, water boils at 212°F. In Baguio City, at an elevation of more than 5,000 feet above sea level, the most reasonable boiling point of water is
a. 95°C
b. 100°C
c. 273 K
d. 300°F

Answer:

The answer is letter A 95°C.

Explanation:

Boiling Point

Boiling point refers to the temperature where the vapor pressure of a liquid substance becomes the same with the external pressure surrounding the liquid. This means that the boiling point of a liquid substance is dependent on atmospheric pressure.

Atmospheric Pressure

Atmospheric pressure is the force per unit area exerted by the weight of the air to the surface or substance below it.

Relationship of Boiling Point, Atmospheric Pressure, and Elevation

Boiling point and atmospheric pressure decreases as the elevation increases. The main reason behind this is because air is less dense at higher altitudes, meaning they have low atmospheric pressure at higher altitudes.

Since the atmospheric pressure is lower at elevated areas, this means that the vapor pressure of the liquid is also lowered in order to reach its boiling point, hence, boiling point would also be lower at higher altitude.

Analysis

The problem gave us two factors to consider, the boiling point of water at sea level which is 212°F and an elevation 5000 feet above sea level.

With these factors to consider we must know which among the choices is the most reasonable boiling point of water at 5000 feet above sea level.

From the explanation above, boiling point decreases as the elevation increases, hence we must choose the temperature that is lower than 212°F

  • Letter A - 95°C; 95°C = 203°F, therefore, it is lower than 212°F
  • Letter B - 100°C; 100°C = 212°F, therefore, they are just the same
  • Letter C - 273 K; 273 K = -459.67°F, it is lower that 212°F but it is way too low and there is no negative value for boiling point
  • Letter D - 300°F; 300°F is obviously higher than 212°F

So the most reasonable boiling point of water at an elevation more than 5000 feet above sea level is letter A, 95°C.
