If you were to travel to Denver, the mile high city, air pressure is reduced. This makes it easier for gas molecules to escape the liquid, hence the boiling point lowers. On the other hand, when pressure increases, gases have a harder time escaping the liquid so the boiling point must increase.

How does pressure affect boiling point?
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.
What happends to the boiling point of a substance when pressure above it decreases?
The boiling point will also decrease in this case.
Hydrocarbon boiling points increase the number of carbon or decrease?
the boiling points decrease on hydrocarbons as the length of the chain and the weight increases. the melting points increase with length and weight increase. Hope this helps.
Why an increase in vapour pressure stop boiling?
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.
How can the boiling point of a liquid be raised without adding soluble impurity?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, or the pressure above the liquid. So, to increase the boiling point without adding a solute, one can increase the pressure above the liquid.
Why the boiling point of water is 98 in Kaghan?
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.
What is the term for the Boiling of a liquid caused by decrease in pressure rather than by an increase in temperature?
Cavitation
How does the boiling point of a liquid vary with pressure?
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.

What happends to the boiling point of a substance when pressure above it decreases?
The boiling point will also decrease in this case.
How Does Pressure Affect The boiling points?
The boiling point of an element or a substance is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid.Vapour pressure or equilibrium vapour pressure is the pressure of a vapour in thermodynamic equilibrium with its condensed phases in a closed container.The vapor pressure of any substance increases non-linearly with temperature.Suppose we are at the boiling point....As pressure of surroundings increases we need to increase the vapour pressure so as to make the vapour pressure equal to the surrounding pressure...Now, to increase the vapour pressure we will have to increase the temperature....So When presure increase boiling point increases...when it decrease boiling point decreases...
If you increase the pressure the boiling point will increase or remain same?
if you increase the pressure, the boiling point (temperature) will also increase.
Do the boiling point of water directly proportional to pressure?
Yes, if you decrease the pressure, boiling point will also decrease and vica versa.
The result of the weight of the column of air pushing down on an area?
Air pressure, barometric pressure, the boiling point of water.
What Two types of this are boiling and evaporation?
decrease and increase
Hydrocarbon boiling points increase the number of carbon or decrease?
the boiling points decrease on hydrocarbons as the length of the chain and the weight increases. the melting points increase with length and weight increase. Hope this helps.
