Question

As you climb a mountain, the boiling point (temperature) of water:

1. decreases
2. remains at 100° C
3. increases

Answer 1

1, decrease

Step-by-step explanation:

At higher altitudes, air pressure is lower. When atmospheric pressure is lower, such as at a higher altitude, it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.
