As the altitude increases, atmospheric pressure decreases. In order to boil the liquid's vapor pressure should match the enviromental pressure, so water boils at a lower temperature at higher altitudes. But whether it boils faster or not, that depends on the heat provided.

∙ 14y agoWater boils at a 100 degrees Celsius when the atmospheric pressure is at 1 atmosphere. As the elevation increases, the atmospheric pressure increases in turn raising the boiling point of water. So, it will take longer for the water to boil.

∙ 12y agoYes it does, if you can't go up a mountain then try the following experiment to create the same effect
materials:
- a vacuum pump with a glass bowl attached to it
- a beaker with water at room temperature (about 20 degrees Celsius or 68 degrees Fahrenheit)
method:
place the beaker on a flat surface;
put the bowl over the beaker and turn on the vacuum pump.
the more water you've used in this experiment, the longer it will take to make it boil!

∙ 12y agoIt boils faster. At higher altitudes, the air pressure is low. So water is more eager to expand and become gaseous (Water is less pressed down upon by the atmosphere)
Wiki User
∙ 14y agoWater boils at a lower temperature at a higher altitude.
Wiki User
∙ 14y agoActually because of the higher altitude you have less atmaspheric pressure which means that it takes less heat to boil water.
Wiki User
∙ 14y agoYes, it boils at a lower temperature because there is less air pressure bearing down on its surface to prevent the escape of vapour.
Wiki User
∙ 14y agoYes. Atmospheric pressure is lower at high altitudes, allowing water to vaporize or boil more easily, therefore, at lower temperature.

Why does water boil faster at high altitude than at sea level?
There's a smaller column of air pressing down at high altitudes, so air pressure is less.
How would the boiling point of a liquid change by measuring it in Denver altitude-5000ft?
Water normally boils at 100 °C. High elevation cooking generally takes longer. In Denver, water boils at approximately 95 °C. Boiling point of a liquid lowered in Denver.
What liquids boil?
Heat can make water boil, like when you put a pot of water on the stove on high!
Why is cooking time longer at high altitudes?
It doesn'tActually, at higher elevations, water boils sooner rather than later. At higher altitudes, air pressure is lower. The reduced air pressure lowers the temperature at which water boils in an open container. So, water actually boils faster at higher altitudes, but it takes longer to cook foods because the water boils at a lower temperature. This lower temperature slows down the physical and chemical changes that take place when foods are cooked in water.(Sometimes it can take water longer to boil at higher altitudes simply because it is often colder and windier at high altitudes (if you camping), and so it will take longer to heat the water).If you are taking a chemistry class right now, you might recall your teacher talking about Gay-Lussac's law of P1/T1 = P2/T2. Therefore, given that the volume is constant, as the pressure changes from 1 ATM to a lower number, say .5, temperature must also change in proportion to the atmosphere to fit the equation. The temperature would decrease by 1/2.See the Related Questions link to the left for more information about how barometric pressure and elevation effect the boiling point of water.Following the idea of higher altitudes/lower atmospheric pressure, there will be less initial dissolved oxygen in the higher altitude water compared to a pot of water in lower altitudes. This will decrease the quantity of bubbles (oxygen escaping from the water) you see as the water heats but before the water actually begins to boil. If you confuse these bubbles with boiling it will seem as though you are not reaching a boil as quickly as when there is more dissolved oxygen and more bubbles.The following correction is from a science major with chemistry minor: the above is almost true, but Gay-Lussac's law is expressed a different way. It is P1/T2=P2/T1. What the above formula describes is Boyle's law (P1/T1=P2/T2).
Is it true that boiling point remain constant in all altitudes?
No, the boiling point decrease at high altitudes.
Why does water boil faster at high altitude than at sea level?
There's a smaller column of air pressing down at high altitudes, so air pressure is less.
In what particular place the water will boil faster?
At high altitude
Do high altitudes make you run faster?
NO
Does altitude affect clocks?
yesclocks tick faster at high altitudes
Why vegetables are cooked with difficulty at a hill station?
At high altitudes, the boiling point of water is lower than at sea level. Therefore, you may have to boil vegetables for longer.
How do you think boiling of water will change on sea level as compared to boiling water on a mountain top?
I think that the temperature required to boil water is lower at high altitudes (where the atmospheric pressure is lower) than at sea level.
How long does it take to boil water at sea level?
That depends directly on the altitude. On top of Mt Everest, the boiling point of water is so cool that it is nearly impossible to cook anything. At pretty high altitudes, you might have to boil the egg for an hour.
How do you cook at high elevations?
Water and other fluids boil at a lower temperature at high altitudes. When a liquid boils its temperature stops rising. If a recipe that calls for cooking something for a certain amount of time after it begins to boil, there is an implied assumption the cooking process is taking place at sea level. Therefore, you need to adjust your cooking time for a longer period of time at higher altitudes since the cooking temperature is lower than what it would be at sea level. That is why it takes longer to boil an egg in, say, Denver, Colorado than it does in Miami, Florida. See Sources and related links for various links to cooking at high altitudes.
Are parachutes faster at high altitudes or low altitudes?
it is faster at a higher altitude because there are less air pressure when you're away from the Earth. There are more air pressure as you come to Earth so it becomes slower.
How does water move from high altitudes to specific waterways?
Gravity/downhill.
How would the boiling point of a liquid change by measuring it in Denver altitude-5000ft?
Water normally boils at 100 °C. High elevation cooking generally takes longer. In Denver, water boils at approximately 95 °C. Boiling point of a liquid lowered in Denver.
