How does change in pressure affect the boiling point of a compound?
An increase in pressure raises the boiling point of a compound because it requires more energy for the molecules to overcome the increased pressure and escape into the gas phase. Conversely, a decrease in pressure lowers the boiling point because less energy is needed for the molecules to escape.
How does abnormally low pressure affect the boiling point of a compound?
Abnormally low pressure decreases the boiling point of a compound because it reduces the pressure exerted on the liquid, making it easier for molecules to escape into the gas phase. This results in a lower energy requirement for the liquid to vaporize, lowering the boiling point.
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.
The temp of boiling water in Celsius?
The temperature of boiling water in Celsius is 100 degrees.
What is the Boiling point of water at 6 barg?
The boiling point of water at 6 barg (bar gauge pressure) is approximately 152.9°C. At this pressure, water requires a higher temperature to boil compared to its boiling point at standard atmospheric pressure (100°C).
Which compound below has the lowest boiling point at standard pressure AlI3 NaI MgI2 HI?
NaI has the lowest boiling point at standard pressure because it is a molecular compound with weaker intermolecular forces compared to the other compounds listed, which are all ionic compounds. Ionic compounds generally have higher boiling points due to stronger electrostatic interactions between ions.
How does change in pressure affect the boiling point of a compound?
An increase in pressure raises the boiling point of a compound because it requires more energy for the molecules to overcome the increased pressure and escape into the gas phase. Conversely, a decrease in pressure lowers the boiling point because less energy is needed for the molecules to escape.
How does abnormally low pressure affect the boiling point of a compound?
Abnormally low pressure decreases the boiling point of a compound because it reduces the pressure exerted on the liquid, making it easier for molecules to escape into the gas phase. This results in a lower energy requirement for the liquid to vaporize, lowering the boiling point.
What is the boiling point of a water?
The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit at standard pressure.
What is the effect of an insoluble solid such as glass on the boiling temperature of a liquid?
If the solid is insoluble, it will have little or no effect on the boiling point. If it is soluble, it will raise the boiling point.
How pressure attract boiling point in cyclohexane?
It is impossible to 'attract' any boiling point (whatever that may mean):Boiling point is a physical property of a particular liquid compound depending on pressure.
What is the boiling point of a liquid at a pressure of 101.3 kPa?
Each liquid has a different boiling point; 101,3 kPa is he standard atmosphere pressure (atm).
What is the boiling point of deionized water?
212ºF or 100ºC at standard pressure (1 atmosphere).
Determination of melting pont of ice and the boiling point of water?
At standard pressure: - Melting point of ice: 0 0C - Boiling point of water: 100 0C
Why is the boiling point of a substance at low pressure lower than the boiling point at standard pressure?
At low pressure, less energy is required for molecules to escape the liquid phase to become gaseous. Conversely, at high pressure, the boiling point is increased.
How hot is 100'c with water?
It is the water boiling temperature under atmospheric pressure.
What is the boiling point of a compound?
as far as i know the B.Pt. is defined as " when the vopour pressure of the liquid is equal to the atomospheric pressure then it is said to be the boiling point of the liquid." similarly "when the vapuor pressure of the solid is equal to atmospheric pressure then its corresponding temperature is called melting point of that compound." so a compound may be a low melting one but the same compound may be ahigh boiling liquid. this is due to the inter & intra molecular forces that exists in the molecules. so there is no specific equation that a compound having a m.p. of 102c will have a b.pt. of some particular value.
