"Boiling point elevation" is a so-called "colligative property."

Explanation:

And by definition the effect depends on the number of particles in solution. We could use "molarity", mol*L^-1, to express the number of particles. But because molarity is dependent on temperature (i.e. solution can become LESS dense with increasing temperature), we typically use another concentration term, "molality"-="moles of solute"/"kilogram of solvent" to express the number of particles per mass of solvent.

At LOW concentrations, "molality" is equivalent to "molarity".
