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...

∙ 13y agoAt sea level water boils at 100 C / 212 F; but on top of Mount Everest it boils at 69C / 156 F. The boiling point increases with pressure increase, the link below shows a chart of water and the effect of pressure on the boiling point.

How does operating temperature affect distillation?
Increasing pressure hinders the ability of two fluids with different boiling points to separate. Reducing pressure does the opposite and makes the fluids easier to separate based on boiling point.
How can changing water pressure affect boiling point?
Increasing the pressure increases the boiling temperature
How does pressure affect the boiling point of gold?
At low pressure the boiling point is lowered and inverse.
Why boiling point of water is not fixed?
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
Why are boiling points of liquids usually reported along with the pressure at which the boiling point was measured?
Melting points of pure solids are reported without including the pressure. This is because it is assumed that standard laboratory conditions of 1 BAR, or 25 degrees Celsius were used.
How do boiling points affect evaporation?
Boiling point is where the vapor pressure of a liquid equals the ambient pressure. The closer you are to the boiling point, the more driving force there is for the liquid to evaporate until it saturates the surrounding air.
Why is it important to state the pressure at which boiling points occur?
It is important because boiling points are dependent onthe pressure.
How does operating temperature affect distillation?
Increasing pressure hinders the ability of two fluids with different boiling points to separate. Reducing pressure does the opposite and makes the fluids easier to separate based on boiling point.
How does pressure affect the boiling point of gold?
At low pressure the boiling point is lowered and inverse.
How can changing water pressure affect boiling point?
Increasing the pressure increases the boiling temperature
How does pressure affect boiling point of Methane?
At low pressure the boiling point is lowered and inverse.
Why boiling point of water is not fixed?
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
How does abnormally low pressure affect the boiling point of a compound?
lower pressure means a lower boiling point.
What is the relationship between pressure and the boiling points of liquid?
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.
Why are boiling points of liquids usually reported along with the pressure at which the boiling point was measured?
Melting points of pure solids are reported without including the pressure. This is because it is assumed that standard laboratory conditions of 1 BAR, or 25 degrees Celsius were used.
Do all the liquids at their boiling points have same vapour pressure?
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
Could you tell me 3 examples from everyday life which show the affect of pressure and impurities on the melting and boiling points?
hey i really need help, can u answer the Question
