Answer:
  A hypotonic solution in which it contain more solute than solvent.example a lot of salt (solute)
dissovled in water (solvent)

isotonic  solution in which solute and solvent are equally distrubuted for example a cell normally wants to remain in an isotonic solution where concentration of liquid inside it is equal to the concentration of the liquid outside of it.

hypertonic solution in which contains more solvent than solute.

the elevation of boiling point (ΔTb) is directly proportional to the molal concentration of
the solute in a solution. Thus
ΔTb ∝ m 
or ΔTb = K_bm 
Here m (molality) is the number of moles of solute dissolved in 1 kg
of solvent and the constant of proportionality, Kb is called Boiling Point
Elevation Constant or Molal Elevation Constant (Ebullioscopic
Constant). The unit of K_b is K kg mol-1.
