The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
Water boils at a lower temperature at higher altitudes because water boils when the vapor pressure of the heated water matches the pressure of the atmosphere pushing downward. Since there is a higher atmospheric pressure at sea level than in say a mountain, the temperature needed to boil water decreases.
Boiling point of a liquid is the temperature at which its vapour pressure equals with the atmospheric temperature . So as in mountains the atmospheric pressure is less than that in ground less temperature is required to reach this condition and hence this occures ..
The boiling point of water will depend on the atmospheric pressure. The relationship is that the higher the pressure, the higher will be the boiling point, because the boiling point is when the vapor pressure of the liquid equals the atmospheric pressure. Up on a mountain, or high hill, the atmospheric pressure is lower, and therefore the boiling point is lower. Again, because water will boil when its vapor pressure is equal to the atmospheric pressure.
At lower pressure (up high in the mountains, or in a vacuum room) all liquids have lower boiling temperatures.
I think that the temperature required to boil water is lower at high altitudes (where the atmospheric pressure is lower) than at sea level.
Due to lower atmospheric pressure at altitude, water will boil at lower temperature.
The temperature of boiling water at sea level is 100 The temperature of boiling water at sea level is 211.149°F.
Boiling and evaporation are basically the same change of phase -- from a liquid (water) to water vapor or steam. One of the factors of when this phase change occurs is "pressure". You can make water "boil" in a closed container without adding "heat" by simply by rapidly expanding the size of the container. Atmospheric pressure (literally the 'weight' of the air above) at mountain altitudes is less that it is at sea level. As a result, it takes less heat to make water evaporate or "boil" on top of a mountain.
First understand that the boiling of water occurs when the energy of water molecules is equal to the vapour pressure... (i.e energy of water is equal to the external pressure due to the atmosphere)... above sea level the atmospheric pressure is lower hence low energy is required... hence water boil at low temperature...
I think that the temperature required to boil water is lower at high altitudes (where the atmospheric pressure is lower) than at sea level.
Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.
The boiling temperature of water is dependent on the surrounding pressure. And air pressure decreases as you get higher up. As pressure decreases, so does the boiling point. This means that the water will start to boil faster on the mountain, but it will boil at a lower temperature. At a lower temperature, food takes longer to cook.
It is the effect of air pressure. The air pressure at the top of a mountain is less than the air pressure at sea level. The effect of air pressure on a water surface is to prevent or oppose water molecules escaping from the surface. The greater the air pressure, the more heat energy is needed to allow the water molecules to escape and so at sea level the water will boil at a higher temperature than if it were on top of a mountain.
Because in the mountaintop the pressure is lower than in the sea level; I think.
Due to lower atmospheric pressure at altitude, water will boil at lower temperature.
As you get higher above sea level, air pressure decreases. Water boils at a lower temperature when the air pressure is lower. When the water temperature is lower, pasta and anything else takes longer to cook.
As air pressure drops over the water surface the boiling point will drop and vice versa. So a kettle of water will boil at a lower temperature at the top of a mountain than at sea level because there's lower air or atmospheric pressure at the mountain top. Pressure is proportional to boiling point
Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.

The boiling point varies in the same direction as the pressure. At the top of a mountain the air pressure is lower so water boils at a lower temperature. In a pressurized boiler system the pressure is higher so water boils at a higher temperature.
Because there is less air pressure.
