Answer» SOLUTION :(i) FREEZING POINT is difined as the temperature at which the solid and the liquid states of the substances have the same vapour PRESSURE. (ii) When a non volatile solute is added to water at its freezing point, the freezing point of water is lowered from `0^(@)C.` The lowering of freezing point of the solvent when a soute is added is called depression in freezing point `Delta T_(f).` (iii) `Delta T_(f) = T_(f)^(@) - T_(f)`
