The atmospheric pressure decreases and so does the boiling point. Water boils when it has enough energy to produce vapour anywhere within the liquid.
On top of Mt Everest water boils before it reaches 70 ºC. Mountaineers cannot have a hot drink because at ~65 ºC cools too much and does not warm up the mountaineers. To make the water boil at a higher temperature, a pressure cooker must be used. This increases the pressure and, therefore, the boiling point of the liquid.
so, theoretically, on a high mountain you cannot boil an egg because the water will never get to the egg's hardening point.
ANSWER
The temp decreases..ie. water "boils" at a lower temp the higher you go. So when you reach the top of the mountain and you are starving, you get out the little stove to boil water. The vacuumed packed shaved beef directions say "boil for 30 mins. then serve hot". IT WILL NOT BE HOT! It may still be frozen. If you are up really high, read "boil 3 hours or untl hot!!
It's the other way around. A decrease in pressure is often caused by a decrease in altitude. When pressure is lower, boiling point also lowers as individual molecules can vaporize more freely.
When there is an increase in altitude, the pressure for the boiling point is lower. A decrease in pressure causes a lowering of the boiling point.
That was wrong, air pressure decreases, and the temperature also decreases.
because its lower pressure at higher altitudes because there is less air so the water molecules are farther apart which makes it boil at lower temps
An increase in altitue leads to a lower pressure which results in a lower boiling point.
The boiling point increase also.
It gets colder
The rate of change of air pressure as a function of increasing altitude decreases with increasing altitude.
Increasing the temperature the number of particles remain constant and the pressure increase.
As altitude increases (i.e. when you get higher) pressure falls off inversely; a change near the higher reaches will not have as much of a pressure differential as the same distance change lower down.
A definition of boiling point is when the vapor pressure of the liquid equals the ambient atmospheric pressure, thusly if you increase the pressure the vapor pressure must also increase and to do this you have to increase the temperature. Shinolaman
If you put pressure on ice it will melt.
This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
The boiling point of water is dependent on environmental factors and the presence of solutes. In this case the pressure of the system on the water serves to increase the boiling point of water. The higher pressures increase boiling points while lowering pressure decreases it.
As altitude increases, pressure decreases, so boiling point decreases, so the liquid would boil at a lower temperature and would not be able to get as hot and remain a liquid. As pressure is increased, boiling point increases, meaning the liquid could get hotter than normal and remain a liquid.PV=nRT - pressure x volume = the number of moles x constant x temperature
If performed correctly, your altitude should increase.

as altitude rises less there is less atmospheric pressure

the temperature decreases as you increase in altitude.
