Boiling point elevation
The tendency of a solute to change the boiling point of a solvent is called boiling-point elevation. This occurs because the presence of the solute disrupts the solvent's ability to form vapor, therefore requiring more heat to reach the boiling point.
Liquids in a pure state have a specific boiling point.Water, for example, boils at 100 oC at 1 atm. However once there are impurities in the liquid the boiling point will be elevated. The degree of elevation depends on the quantity of impurity in the liquid.
This is the property of freezing point depression and boiling point elevation. This is because of the solute absorbing the energy added to the system to heat its own molecules and so it would require more energy to boil the solvent. Likewise for freezing point depression, the molecules retain more energy.
The solution freezes at a lower temperature and boils at a higher temperature.
The presence of solutes in a solution alter the ability of solvent molecules to interact. This affects the ability of the solvent to go through phase changes. These are called colligative properties. The basic colligative properties are boiling point, freezing point, osmotic pressure, and vapor pressure.

I have researched the Internet on your behalf and found a web site that appears to address your question. The link to the web site is called RAOULT'S LAW AND NON-VOLATILE SOLUTES and is displayed directly below this window.

A rag dampened with solvent is called a solvent-saturated rag.
The change in the freezing point of a solvent by the addition of a solute is called freezing point depression. This phenomenon occurs because the presence of the solute disrupts the crystal lattice formation of the solvent, requiring a lower temperature for freezing to occur.
