explain to me how higher elevation causes less degrees in boiling points?

Question

i dont get how this causes less energy to be used and less airpressure >:( explain these to me

Answer 1

The atmosphere is less dense, the atmospheric pressure is less at high altitudes. The boiling point of water is the temperature at which the vapor pressure of water equals the pressure of the atmosphere. If one is a mile high in Denver, the atmospheric pressure is less, so the vapor pressure of water needs to be less to boil, that takes a lower temperature, so water (and other liquids) boil lower at higher elevations.

Answer 2

It's been a long time since chemistry. The higher the elevation the lower the atmospheric pressure. The air molecues are further apart causing water to boil with less heat. What most people don't understand is that the water is not as hot as at sea level. You can actually boil water at room temperature if you put the water in a sealed beaker and suck out the air with a vacuum. Kinda cool holding boiling water in your hand.
