In steam distillation, the boiling point of a mixture of water and the volatile compounds being distilled is typically lower than 100 degrees Celsius. This occurs because the presence of steam reduces the partial pressure of the volatile components, allowing them to vaporize at a lower temperature. Therefore, while water itself boils at 100 degrees Celsius, the actual boiling point during steam distillation does not exceed this temperature due to the combined effects of pressure and the nature of the compounds involved.

If the components of a liquid hydrocarbon are to be separated by fractional distillation the components should have?
The components of a liquid hydrocarbon should have significantly different boiling points to be effectively separated by fractional distillation. Ideally, the boiling point differences should be at least 25-30 degrees Celsius to allow for efficient separation during the distillation process. Additionally, the components should ideally be non-volatile and have similar chemical properties to prevent overlapping during separation.
Why is it preferable to add boiling stones into the mixture in the distillation flask during distillation?
The reasons are:- to avoid splashing due to overheating- to calm the boiling
What is the degrees on Venus during night?
About 480 degrees Celsius.
During distillation what temparture should the distillate be colllected?
During distillation, the temperature at which the distillate is collected depends on the boiling point of the component being distilled. For simple distillation, the collection typically begins when the temperature reaches just below the boiling point of the desired liquid. For fractional distillation, the collection is more precise and may involve monitoring specific temperature ranges to separate components based on their boiling points. It's important to maintain a consistent temperature to ensure efficient separation.
How does boiling point affect the location at which a substance is removed during the procces of fractional distillation?
In fractional distillation, the boiling point of a substance determines its vaporization and condensation behavior within the distillation column. Substances with lower boiling points vaporize first and ascend the column, where they can be collected at higher points. Conversely, substances with higher boiling points remain in the column longer and are collected at lower points. This difference in boiling points allows for the effective separation of components based on their volatility.
What is the optimal temperature for ethanol reflux during the distillation process?
The optimal temperature for ethanol reflux during distillation is typically around 78.3 degrees Celsius.

The boiling point of both the liquids should be known during separation by fractional distillation method.why?
Knowing the boiling points of the liquids is important during fractional distillation because the process relies on differences in boiling points to separate the components. By knowing the boiling points, the distillation can be conducted at the appropriate temperature to ensure efficient separation of the components based on their boiling point differences.
What type of weather does Neptune have during night and day?
Day: -225 degrees Celsius Night: -223 degrees Celsius -382 Celsius degrees in the morning and-230 degrees Celsius
What is to purify by boiling and condensing?
This is known as a distillation. Ethanol and water can be separated using this process because their boiling points are different which allows them to be "boiled off" at different temperatures.
What is the Celsius of the moon?
During the day it can reach 123 degrees Celsius and at night can dip to as low as -233 degrees Celsius.
What is the degrees on Venus during night?
About 480 degrees Celsius.
What information can be obtained from a distillation temperature chart?
A distillation temperature chart provides information about the boiling points of different substances in a mixture, helping to determine the separation and purity of components during distillation.

What is the maximum temperature recorded on the thermometer during distillation?
The maximum temperature recorded on the thermometer during distillation is the boiling point of the liquid being distilled. This is the temperature at which the liquid changes state from liquid to vapor. It is important to closely monitor this temperature to ensure proper separation of components during distillation.
What happens to its temperature when water is boiling?
The temperature of boiling water stays the same. At sea level, that is 100 degrees Celsius or 212 degrees Fahrenheit. At higher elevations, say on a tall mountain, the boiling point of water is less and less, the higher you go.
