The presence of the impurities will cause the boiling points to rise (also the melting points to fall). When you add the impurities, the substance doesn't remain pure affecting the boiling point to increase because now, more energy is required to boil the liquid with impurities.
The melting points fall because impure substances require less energy to separate the particles.

Is the melting point of impure water lower or higher than freezing point?
The boiling Point of impure water is 100 degrees celsius
What can be said about boiling point of a liquid?
The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
How does IMF affect the boiling point or melting point of a substance?
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
How does boiling point and melting point find a substance?
what is the melting point and boiling point of substance
Which is true of a melting point and a boiling point?
Melting point: at this temperature a solid become a liquid.Boiling point: at this temperature a liquid become a gas.
How does impurities affect the boiling point of liquid?
Let's say substance A is the substance and substance B is the impurity. The boiling point of the mixture would be somewhere between that of A and B, depending on the amount of impurities in the mixture.
What may happen to the boiling point of a substance if there are impurities present?
The boiling point won't decrease
Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
How does one increase the melting or boiling point of a substance?
Add impurities (salt and others) to the substance.
Is the melting point of impure water lower or higher than freezing point?
The boiling Point of impure water is 100 degrees celsius
What happens to the melting and boiling point of a substance if it contains impurity?
If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.
What happens when a substance is distilled?
Components are separated depending on the boiling point.
What may happen to the boiling point of the substance if there are impurities present?
The boiling point will increase. The impurities essentially "block" the molecules of the substance from leaving the liquid as a gas, so a higher temp is needed to boil it. see colligative properties.
What may happen to the boiling point of a substance if there are impurities present. Explain in terms of the nature of impurities.?
it might decrease or increase depends on the impurities added.:D
What can be said about boiling point of a liquid?
The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
How does a substance's boiling point determine its state at room temperature?
If the substance's boiling point is lower than room temperature, it is probably a gas. If the boiling point is higher, it will be a liquid.
Why tap water evaporates so fast?
Impurities in water lower the rate of evaporation because impurities increase the boiling point.
