Question

Explain why water has a different boiling point at an elevation of 3000 meters than it does at sea level

Answer 1

This is because the pressure at 3000 meters is lower than at sea level. Therefore, in order for water to change from a liquid to a gaseous state, it requires less energy. Thus, a lower boiling point occurs. 

Answer 2

The lower the pressure the lower the temperature, thus, at 3000 m the pressure is lower, therefore the boiling temperature is lower than at 0 m.

Step-by-step explanation:

Hello,

In this case, the boiling point of water at the sea level is about 100 °C whereas at 3000 m is about 89.5 °C since the pressure at higher altitudes is less than the atmospheric pressure. In such a way, considering a directly proportional relationship between pressure and temperature, the higher the pressure the higher temperature (sea level) whereas the lower the pressure the lower the temperature (at 3000 m)

Best regards.
