WebImpurities lowers the melting point of substances an increases the boiling point , causing them to have a wider range of temperature for melting and boiling.that is the more the amount of impurities in a substances the lower it melting point. A substance boils when the vapor pressure of the liquid will equate the pressure from the outside. 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 ...
