The normal boiling point of cyclohexane is 81.0 degrees Celsius what is the vapor pressure of cyclohexane at 81.0 degrees Celsius?
Dariahemmai
The vapor pressure of anything at its boiling point is 1 atmosphere. That is the definition of boiling point, the vapor pressure is just enough to overcome atmospheric pressure. It could also be stated as: 760 mmHg (torr), 29.92 inHg, 14.696 PSI, 1013.25 millibars, or 0 PSIG.
ImprovedThe problem to answer this Q. correctly, is that the atmosferic pressure is NOT the same as one atmosphere:On sea level and under normal, average weather conditions it is most of the time true, so then the A. is correct.
But high in the mountains cyclohexane will boil at a lower temperature (than 810C) because of the lower (than 1 ATM.) atmosferic pressure.
The above definition of boiling point is CORRECT, but the first statement (The vapor pressure of anything at its boiling point is 1 atmosphere) is NOT

The temp of boiling water in Celsius?
That depends a lot on the pressure - at higher altitudes (less pressure), the boiling point is lower. At standard pressure (1 atm.), the answer is 100 degree Celsius.
Water evaporate at?
Depends on the pressure. The normal boiling point (at 1 ATM of pressure) is 100 degrees Celsius.
What is the boiling point of an aqueous solution that has a vapor pressure of 18.5 at 25 degrees Celsius?
108.7
What is the boiling point of bromine when the external pressure is 75 kPa?
50 degrees Celsius (trust me)
What is the boiling point celsius?
Generally this question is asked in reference to water (which is ~100 degrees Celsius) It should be pointed out that the fact that water boils at 100 degrees Celsius and freezes at 0 degrees Celsius at one atmosphere pressure (760 mm Hg) is not a fluke. It was purposely scaled to to water. In general the boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure acting on the liquid. On Earth in the open air the boiling point of a liquid depends on atmospheric pressure. As a consequence the boiling point becomes lower as the external pressure is reduced - as when you go to the peak of a mountain.
Why is the cyclohexene product able to be purified by distillation?
their boiling point allows them to separated by distillation, dichloromethane (CH2Cl2) boils off at 41 degrees Celsius and cyclohexane (C6H12) boils off at 81 degrees Celsius.
What are the freezing point and boiling point of water in the celsius?
Freezing = 0 degrees Celsius (0oC) Boiling = 100 degrees Celsius (100oC)It depends on the object you are talking about.The boiling point of water is 100 degrees Celsius, and its freezing point is 0 degrees Celsius.
What is the temperature of 100 Celsius in degrees?
100 degrees Celsius is the boiling point of water, which happens to be 212 degrees Fahrenheit at standard pressure
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 temp will water boil in ceelsius?
The water boiling point in Celsius is 100 °C.

What is water's boiling point in degrees Celsius?
The boiling point ot water at the standard pressure (760 mm Hg) is 100 oC.
Boiling point of water at absolute 0 pressure?
0 degrees Kelvin. (Or -273.16 degrees Celsius.)
A liquid unknown is insoluble in water and soluble in cyclohexane and alcohol with a boiling point of 145 C at 658 mm Hg. What is the substance?
To find the substance, you can use a Nomograph Table. Take the observed boiling point and the pressure to find the change in temperature correction. It was found that the actual boiling point was 3.5 degrees off what was stated, so the boiling temperature is 60.5 degrees Celsius. The compound has a boiling point of approximately 60.5 degrees (1) in water and (s) in cyclohexane and alcohol. Chloroform is extremely close to this, with its normal boiling point being 61 degrees Celsius and it matches everything else.
What is the boiling point of liquids?
212 Degrees Fahrenheit,100 Degrees Celsius
What is bolling point of water on the celsius scale?
The nominal boiling point is 100 degrees Celsius. This is for standard pressure (about 1 atmosphere), but the boiling point varies CONSIDERABLY depending on the exact pressure.
What Is the boiling point of the actone?
The boiling point of acetone is approximately 56 degrees Celsius or 132 degrees Fahrenheit at standard atmospheric pressure.
