Never add a boiling chip to a hot liquid, because it can cause immediate boiling over of the solution. If you forget to add a boiling chip before you begin, you must cool the solution before adding one to prevent product loss. "Porous" boiling chips cannot be re-used since the pores inside these stones become filled with liquid on cooling. "Sharp" boiling chips like silicon carbide or coal can often be reused until they become coated with guck and become ineffective.
its pores will filled with liquid after it cooled.
because this can cause bumping.
They absorb water.
Boiling chips are not soluble in water.
the use of boiling chips is that it traps air bubbles and it provides spaces for the solvent vapor can form. When the boiling process is started heated chips will release small bubbles to promote even heating of the solution this will ensure it will not over heat or (worst case scenario) explode. in short it makes the process more safely :D hope it helped
most of the carboxylic acids used during esterification are very volatile. boiling chips are added to maintain a smooth heating of the mixture and to prevent a voilent heating.
Boiling chips are placed in a distillation flask to avoid a phenomenon called "bumping": boiling so violent that it may contaminate the distillation condenser with liquid from a source other than condensate from vapor. Boiling chips accomplish this by releasing small bubble of adsorbed air that reduce the activation energy required for boiling in a gas free liquid. The activation energy arises because the interface formed between liquid and gas requires additional energy, above the heat of vaporization, to be formed because the interface has energy of its own.

you cant
The motivation is to avoid uncontrolled boiling and splashing.
Porcelain chips are used to avoid splashing during boiling of liquids.
no you cant recycle foam, you can reuse it.
just because
To avoid overpressure and splashing during boiling.
Yes, many types of boiling aids.
No. You cant get head lice from chips.
Boiling chips are made up of calcium carbonate or calcium sulfate. Calcium carbonate is typically not flammable, but it will burn when in contact with fluorine. Calcium sulfate in non-combustible.
Porcelain chips (or another material) are added to assure a nonviolent boiling.
