When common salt is dissolved in water,

What is the elevation in boiling point for a one molal solution of a solute in a solvent called?

The rise in the boiling point of a solution containing $1.8 \ g$ of glucose in $100 \ g$ of a solvent is $0.1 \ ^\circ C$. The molal elevation constant of the liquid is .......... $K/m$.

An aqueous solution containing $1 \ g$ of urea boils at $100.25 \ ^oC$. The aqueous solution containing $3 \ g$ of glucose in the same volume will boil at ........ $^oC$. (Molecular weight of urea and glucose are $60$ and $180$ respectively)

What is the molality of a solution of a nonvolatile solute having a boiling point elevation of $7.15 \ K$ and a molal elevation constant of $2.75 \ K \ kg \ mol^{-1}$ (in $m$)?

Which of the following solutions,upon complete dissociation,exhibits the maximum elevation in boiling point?
