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

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 the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.
What is the point at which a liquids vapor pressure equals the atmospheric pressure?
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.
What are the factors that affect the boiling of liquids?
Short answer: Pressure. Long answer: Pressure changes the boiling point of a substance. The higher the pressure, the higher the boiling point, and vice versa. For example, boiling water in the mountains is easier than boiling water at sea level. Note that boiling water is not necessarily hot. You can boil water at room temperature if the pressure is low enough (For example, using a vacuum generator)
Is it true that the boiling point of a liquid remains constant at all altitudes?
No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.
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
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.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
The boiling point.
As external pressure such as atmospheric pressure on liquid increases its boiling temperature?
At high pressure the boiling point is higher.
What is the boiling point of H30 plus?
It does not exist except as part of water - it does not exist in isolation so can have no boiling point as boiling happens when vapour pressure equals the external pressure.
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 pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point
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 the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.
What temperature does water boil and evaporates into steam?
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.
What is the boiling point of bromine when the external pressure is 75 kPa?
50 degrees Celsius (trust me)
What is the approximate boiling point of water when external pressure is 100 atms.?
The temperature is 286 oC.
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
