The boiling point is always above the melting point (we keep pressure constant to keep the example simple).
Ebullioscopic constant - Wikipedia
WebΔHvap is the molar enthalpy of vaporization. Through the procedure called ebullioscopy, a known constant can be used to calculate an unknown molar mass. The term ebullioscopy comes from the Latin language and means "boiling measurement". This is related to cryoscopy, which determines the same value from the cryoscopic constant (of freezing ...

The freezing points of pure cyclohexane and solutions of cyclohexane with a weighed amount of naphthalene were used to calculate freezing ... WebThe cryoscopic measurement (i.e., measurement of depression in freezing point) gives the number of ions formed by the dissociation of an ionic compound. The depression in freezing point is a colligative property and depends upon the number of particles in the solution. The greater the number of particles, the more will be the freezing point. phillis wheatley style
