http://orgchem.Colorado.edu/hndbksupport/dist/boilchip.html Boiling chips are small, insoluble, porous stones made of calcium carbonate or silicon carbide. These stones have pores inside which provide cavities both to trap air and to provide spaces where bubbles of solvent vapor can form. When a boiling chip is heated in a solvent, it releases tiny bubbles. These bubbles ensure even boiling and prevent bumping and boiling over and loss of the solution.
Boiling chips work by creating a zone or area in which liquids boils faster without it being super heated or bumping. This is mostly used in distillation processes and heating.

The boiling point of cyclohexylamine is 134.5C and the boiling point of water is 100C. I would use distillation in order to separate cyclohexylamine and water. Because the b.p. of water is lower, the water will separate first.
Having a low density wood chips float on water.
No, boiling does not affect the polarity of water. What it does is create enough energy for the water molecules to separate from one another. But the water molecules are still polar.
Porcelain chips are used to avoid splashing during boiling of liquids.
Boiling chips are not soluble in water.

boiling chips are not added to the distillation flask. the thermometer bulb is placed in the boiling liquid. the water to the water-jacketed condenser is not turned on.
it takes much longer because they use water in boiling and oil in deep frying
First you mix both chalk and salt in water. From the solution that you get, you can filter the chalk out because it is non soluble in water. As for the salt, all there is to do is to just evaporate the water out.
Distillation, because chloroform and water have different boiling points.

Boiling off the water from a salt solution will separate the solid salt and water (which can be collected by a condenser).
They separate at the boiling point of water, 100o Celsius, because the water boils away and the sodium chloride is left behind.
