when a solute is added to a solvent, the boiling point of the solution is higher than the pure solvent's was, but the melting point of it is lower. i know this is because the intermolecular forces are larger when it is boiling, and smaller when it is melting. i also know that it has something to do with the different forces between solute-solute, solvent-solvent, and solute-solvent. what i don't understand is why intermolecular forces can be strong at one point, yet weak at others. thanks for the help.
