Grade 11 Chemistry Workbook, page 20

Boiling Point

The temperature at which the vapour pressure of a substance eqauls the atmospheric pressure

Melting point

The temperature at which the soild and liquid of a substance phase are at equilibrium

Vapour pressure

The pressure exerted by a vaopour at equilibirium with its liquid in a closed system.

Solubility

The property of a solid, liquid or gaseous chemical substance to dissolve (solute) to dissolve in a solid, liquid or gaseous solvent to form a homogenous solution.

Explain the solubity rule:

Polor and ionic solutes will dissovle into polar and ionic solvents while non-polar solutes will dissolve in non-polar solvents.
