Water usually boils at 212F or 100C at sea level. As you go higher up in the atmosphere (higher altitude), the amount of atmosphere pushing down on you decreases, hence the pressure decreases. Water boils when the vapor pressure of the water equals the atmospheric pressure. Vapor pressure increases with increasing temperature, so when there is less atmospheric pressure, a smaller vapor pressure is required to get the water boiling, hence a lower boiling temperature.
Boiling is when the vapor pressure of a liquid equals the atmoshperic pressure. Since at higher altitudes the atmospheric pressure is lower, the water can attain a vapor pressure equal to this lower atmospheric pressure at a lower temperature.
for water to change from water to a gas (to vaporise) it must break its bonds and overcome the air pressure. In space water would simply boil away immediately.
it is the air pressure which is keeping the water a liquid and not a gas, so as you go to higher elevations, naturally the boiling point begins to become lower and lower.
Water will evaporate at any temperature, It has a certain internal pressure due to KE of its molecules. This is called the vapor pressure. When the vapor pressure equals the external (atmospheric) pressure then the water will boil. Increasing temperature increases the vapor pressure until it equals or exceeds atmospheric pressure. The temperature when this occurs is the boiling point. If the altitude is higher, then the atmospheric pressure is less. So the temperature for the vapor pressure to equal the atmospheric pressure becomes less, so the boiling point is lower.
At higher elevations, there is less air pressure; and the boiling point of liquids varies with pressure.
At higher altitudes the atmospheric pressure is less when compared to that of plains. The lower atmospheric pressure results in lower boiling point of water at high altitudes.
At higher altitudes, the atmospheric pressure is lesser than in sea level. So water molecules need lesser energy to occur the phasechange.
As altitude increases pressure decreases. Using the gas law PV-nrt, as the pressure decreases so does temperature assuming no other variable changes.
it depends on the altitude
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
Reduced pressure lessens the squeezing of molecules, which favors their tendency to separate and form vapor.
Boiling point is dependent on air pressure. Air pressure is dependent on altitude. Durban is coastal, almost sea level. Johannesburg is inland, quite a bit higher. High altitude = low air pressure = low boiling point.
Straight chain isomers have higher boiling points, so the more branched the isomer the lower the boiling point.

Yes, at high altitude the boiling point is lower.
Density Reduces as we climb to a higher altitude
In general, the higher the altitude, the lower the pressure, and the lower the pressure the lower the boiling point.
Ya ........ if you have an egg on the top of high mountain the altitude and less air density causes lower boiling points and when you get higher it reduces the boiling point of the water and it is due to atmospheric pressure.Boiling is directly proportional to atmospheric pressure which becomes lower when we go above the sea level example mountainous areas.

All you have to do to reduce the boiling point of water is go to a higher altitude and boil it.
due to altitude. the higher you get, temperature will decrease as well as pressure.

If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.
The higher the pressure, the higher the boiling point. Boiling occurs when the atmospheric pressure equals the vapor pressure. So, at higher altitudes where the atmospheric pressure is lower, the vapor pressure is also lower which in turn creates a lower boiling point which causes foods to have to cook longer.
