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
What else can I help you with?
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.
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.
Why does lowering pressure cause a liquid to boil?
it becomes easier for the molecules to escape
Why the boiling point of a pure liquid is usually reported along with the pressure at which the boiling point was measured?
The boiling point of a liquid depends on the pressure applied to it: higher pressure raises the boiling point and lower pressure decreases it. By reporting the boiling point along with the pressure, it allows for accurate comparison and reproducibility of experimental results, as different pressure conditions can affect the boiling point.
What is the relationship between boiling point and pressure?
The relationship between boiling point and pressure is that as pressure increases, the boiling point of a substance also increases. This is because higher pressure makes it harder for molecules to escape into the gas phase, requiring more energy to reach the boiling point. Conversely, lower pressure decreases the boiling point as it allows molecules to escape more easily.
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.
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.
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 pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point
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
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.
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?
The boiling point of bromine under a pressure of 75 kPa is approximately 58°C. At this pressure, the boiling point of bromine is lower than its usual boiling point of 58.8°C at standard atmospheric pressure.
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.
What is the boiling point of any substance?
The boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure, causing it to change from a liquid to a gas. The boiling point varies depending on the substance and the external pressure.
