The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases.
This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
The boiling point of water increases on adding impurities because the boiling point of the impurities also adds up to the boiling point of water thus increasing it.
The presence of impurities in water lowers its freezing point if the impurities are dissolved, otherwise not.
cause the impurity will have a differant freezing point
It depends what the impurities are and their concentration.
Dissolved particles (ions, molecueles) will make the melting point somewhat lower and the boiling point higher.
The freezing point decrease in the presence of a solute.
don't no
Yes, impurities have important effects on the melting and boiling point of materials.
Adding impurities lowers the melting point and raises the boiling point.
melting point decreases with pressure and increases with impurities (like saw dust). boiling point increases with impurities and also increases with pressure.
Soluble impurities (that is, impurities that are included within the crystal matrix) tend to lower the observed melting point and broaden the melting point range. Insoluble impurities have no effect on the melting point. Found from website: http://swc2.hccs.edu/pahlavan/2423L1.pdf
Impurities will usually lower the melting point of an organic compound. Impurities also increase the range of melting points in the compound. This means the temperature needed for melting isn't consistent.

generally addition of impurities lowers the melting pointand increases the boiling point
melting point decreases with pressure and increases with impurities (like saw dust). boiling point increases with impurities and also increases with pressure.
Depending on what is in it, the boiling point will either rise or fall.
To increase MP and BP point of Zinc u should add some impurities in it. The addition of impurities always decreases the melting point .

It varies. A saturated solution of NaCl in water increases the boiling point, higher than 100oC. I suppose most impurities increase the boiling point.
The boiling Point of impure water is 100 degrees celsius
Add impurities (salt and others) to the substance.
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.
By adding salt it means that you are adding an impurity into the water. Impurities can lower the boiling point, while increasing its melting point.
