Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.

Add the value obtained for ΔTb to the … Webb6 nov. 2024 · The boiling point is raised and the steam must have the same temperature as the liquid; so steam will be hotter. The evaporation needs more energy (since it adds an entropically unfavorable distillation to the evaporation) so the steam is still at 100°C. The temperature drop at the border is reminiscent of a thermocouple.
