A definition of boiling point is when the vapor pressure of the liquid equals the ambient atmospheric pressure, thusly if you increase the pressure the vapor pressure must also increase and to do this you have to increase the temperature. Shinolaman

Why does pressured water have a raised boiling point?

Boiling is the phenomenon in which saturated vapour pressure becomes equal to the external pressure. Hence as we increase the external pressure then the boiling point has to increase so as to attain that pressure


How can a substance boil to a higher temperature with the same rate of heat provided?

A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.


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...


What does an increase in pressure on the surface of water do to the boiling point?

Increasing pressure on the surface of water raises the boiling point of water. This is because higher pressure traps more heat energy in the liquid, thus requiring a higher temperature to overcome the increased pressure and boil.


What processes is most affected by pressure freezing or boiling or melting?

Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.

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 does external pressure affect the boiling point of a liquid and how is this utilized in the food industry?

boiling point of a liquid is affected greatly by the external pressure as the Increase in external pressure = increase in boiling point e.g boiling point of water is 100 degree centigrade under normal pressure i.e 760 torr and has boiling point =98 degree centigrade at Murree HILLS where pressure is less than 760 torr. hence it is approved that external pressure affects boiling point. UTILITY IN INDUSTRY'' BY INCREASING THE EXTERNAL PRESSURE BOILING POINT INCREASES.SO BEFORE B.P OF ANY LIQUID it has much heat in itself which helps in cooking food earlier As in the case of pressure cooker. This property also plays a role in the VACUUM DISTILLATION for such liquids which decompose at lower temperature


Does the boiling point increase with pressure?

Yes, the boiling point of a substance increases with an increase in pressure.

As external pressure such as atmospheric pressure on liquid increases its boiling temperature?

At high pressure the boiling point is higher.


The temperature at which the vapor pressure of a liquid is equal to the external pressure is?

The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.


If you increase the pressure the boiling point will increase or remain same?

If you increase the pressure, the boiling point of a substance will increase. This is because higher pressure leads to stronger intermolecular forces, requiring more energy to overcome them for the substance to boil.


Relation between atmospheric pressure and boiling point?

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 temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?

The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.


What happends to water's boiling point as pressure is increased?
