I believe the boiling point for brine, or salty water, is 117 degrees Celsius. Despite that, yes, that is my understanding of it. On the molecular level, the impurities can "absorb heat" and thus increase the average kinetic energy of the body without increasing the water.

WebComment. Blurt. Anonymous answered. Impurities lower the melting point and increase the boiling point of pure substances, causing them to have a wider range of temperature for melting/ boiling. The more the amount of impurities, the lower the melting point and the higher the boiling point. Thank Writer. WebVerified by Toppr. If we add impurities to a solution boiling point of the solution increases. This happens because the presence of impurities decreases the number of water molecules available to be vaporized during boiling. Once this took place, it takes a greater amount of heat to make the same amount of impure solution to vaporize as it ...
