Estimate the boiling point of a 0.6 molal solution of nacl in water. the boiling point elevation constant of water is 0.51 k/molal. give your answer in °c.

To answer the question above, solve first for the boiling point elevation through the equation,

     ΔT = (Kb)(m)

where ΔT is the boiling point, Kb is constant for water, and m is the concentration. Substituting the known values,

     ΔT = (0.51 K/molal)(0.6 molal)
     ΔT = 0.306 K

The boiling point therefore of the solution is equal to 100.306°C. 

100.306°C

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.
