boiling point elevation

What is the expression of boiling point elevation?
The equation for calculations at dilute concentration
The result is that in dilute ideal solutions, the extent of boiling-point elevation is directly proportional to the molal concentration (amount of substance per mass) of the solution according to the equation: ΔT_b = K_b · b.
Why elevation in boiling point is a colligative property?
Elevation in boiling point and depression in freezing point are colligative properties because both depend only on the number of particles (ions or molecules) of the solute in a definite amount of the solvent but not on the nature of the solute.
At a higher elevation, the lower atmospheric pressure means heated water reaches its boiling point more quickly—i.e., at a lower temperature.
Water at sea level boils at 212 degrees Fahrenheit; at 5,000 feet above sea level, the boiling point is 203 degrees F.
Up at 10,000 feet, water boils at 194 degrees F.

What is boiling point elevation?

Boiling point elevation refers to the increase in the boiling point of a solvent upon the addition of a solute.
When a non-volatile solute is added to a solvent, the resulting solution has a higher boiling point than that of the pure solvent.

MOLECULAR WEIGHT BY BOILING POINT ELEVATION
