Cant be adding salt to water or putting salt on roads.

chmvijay · Answer

colligative properties are properties of solutions that depend upon the ratio of the number of solute particles to the number of solvent molecules in a solution 
here u have mentioned just one example 
when you add the solute to the solvent the boiling point of the solvent increases due to the interaction between the solute and solvent... such type of process u learn mainly in colligative properties chapter

Colligative properties include:mainly 

Relative lowering of vapor pressure
Elevation of boiling point
Depression of freezing point
Osmotic pressure.
