A liquid's boiling point is lower at lower ambient pressure.
boiling point is a property which depends upon the atmospheric pressure. when vapour pressure of water is equal to external is called its boiling point.. if pressure is equal to atmospheric pressure ,boiling point is 100 degree celcius.
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.

As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
The boiling point is more sensitive to pressure than the melting point due to the fluidity of liquid. Liquids move around more when pressure is placed on them, as they're already moving around naturally without the extra pressure.
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
The boiling point of ammonia at atmospheric pressure is -33.34oC.
The normal boiling point(also called the atmospheric boiling point or the atmospheric pressure boiling point)is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure at sea level, 1 atmosphere.The normal boiling point of water is about 100 degrees Celsius at a pressure of 1 ATM (i.e., 101.325 kPa).General Useful Information:The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure, but the environmental pressure may or may not be equal to the atmospheric pressure at sea level, 1 ATM.If the surrounding environmental pressure is less than atmospheric pressure, then the boiling point is less than the normal boiling point.If the surrounding environmental pressure is greater than atmospheric pressure, then the boiling point is greater than the normal boiling point.At the boiling point, adding enough heat to the liquid will cause the liquid to vaporize (that is boil or form a gas).
in lowland the atmospheric pressure is higher so the boiling point will be higher,in highland atmospheric pressure is low so the boiling will be low

because otherwise the measurement will be different. This is because the boiling point of thingss is changes at a low atmospheric pressure.
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
At high pressure the boiling point is higher.
This temperature is called the boiling point, and indicates the temperature at which a liquid will assume a gaseous state, given the addition of the heat of vaporization.That is the boiling point.
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c
Its vapor pressure equals atmospheric pressure.
