The molal elevation constant is the ratio of elevation in boiling point to molality of solution.
ΔTb=Kb×m
Kb=

ΔTb

m

Here, Kb= molal elevation constant
ΔTb= increase in boiling point
m= molality of solution
Due to solute presence in solution, the solution's boiling point is greater than the pure solvent's boiling point. This is called elevation in boiling point (ΔTp).
