Water's boiling points shouldn't be affected with impurities in it, unless it has been chemically altered on a mollecular scale, which couldn't be caused by impurities in the water. The only factor that affects waters' boiling point is pressure, for example, mars' air pressure is a lot less than earths', and the boiling point of water there is 23 degrees celcius.
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
Boiling point is themperature when a liquid is transformed in a gas.

Separation is possible by distillation because boiling points are different.
possibly if it has been contaminated by other substances (as compared to original boiling point - it seems as though it has 2 different boiling points) things such as sodium chloride (table salt) raise the boiling point of water and lower its melting point note though that a pure liquid can never have 2 different boiling points - the boiling point is a property of a a liquid and will never change no matter what. alternatively if the fluid concerned is a mix of 2 different liquids (eg. alcohol mixed in water) the liquid with the lower boiling point (eg. alcohol) will boil off first, then the remaining fluid will continue heating up until the 2nd boiling point is reached (eg. of water). thus the fluid seems to boil at 2 different temperatures
The boiling point is the temperature at which a substance boils. Different substances have different boiling points. The boiling point of water is 100 degrees Celsius. You have to have an accurate thermometer to measure boiling point.
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c
The melting point of impure water is lower than the freezing point. Impurities disrupt the crystalline structure of water, making it harder for the water molecules to align and freeze. This results in the impure water needing to be cooled to a lower temperature before it freezes.
In fractional distillation, ethanol and water can be separated because they have different boiling points. Ethanol has a lower boiling point than water, so when the mixture is heated, the ethanol vaporizes first. The vapor is then condensed back into liquid form, resulting in separate fractions of ethanol and water.
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.
Pure water is a non-conductive substance that is toxic to life, and corrosive of most metals. Impure water is water that has impurities, such as salts, hardness, metal ions, and so on.
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.
