in short, Atoms must vibrate to break their bonds I.E. from solid state, to liquid state to gas state. with a HIGH pressure the atoms must vibrate faster to become hotter to over come the pressure surrounding it. as pressure decreases, less energy is needed to break the bonds and over come the surrounding pressure, and with that a LOWER amount of energy is needed in LOWER pressure.

Because boiling point of a liquid is directly proportional to pressure inside the container in which it is being boiled.

When pressure decreases, the molecules of the liquid requires less energy to escape the liquid surface.

What happends to the boiling point of a substance when pressure above it decreases?

The boiling point will also decrease in this case.


Do the boiling point of water directly proportional to pressure?

Yes, if you decrease the pressure, boiling point will also decrease and vica versa.


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 effect of decreased pressure on the boiling and freezing point?

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.


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.


A decrease in vapor pressure will cause?

It will result in a decrease in the boiling point of a liquid, among other things.


As you go to higher elevations above sea level the boiling point of water?

as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.


When a liquid sample is taken from sea level to a higher elevation what happens to the external pressure on the liquid and the boiling point of the liquid?

atmospheric pressure is lower and the boiling point is less


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...


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 are the three properties of a solution?

1. Vapor pressure lowering: the decrease in vapor pressure with increasing the number of solute molecules in solution. 2. Boiling point elevation: the increase in boiling point with increasing number of solute molecules in solution. 3. Freezing point depression: the decrease in freezing point with increasing number of solute molecules in solution. 4. Osmotic pressure
