Impurities boiling point
Witryna1 sie 2024 · The reason for impurities lowering the melting point yet increasing the boiling point is because the impurities stabilise the liquid phase, making it more energetically favourable. This extends the liquid range to lower temperatures (lowering the melting point) and to higher temperatures (raising the boiling point). Witryna4 wrz 2011 · 53. 0. For starters, you can raise the boiling point much higher than that. I believe the boiling point for brine, or salty water, is 117 degrees Celsius. Despite that, yes, that is my understanding of it. On the molecular level, the impurities can "absorb heat" and thus increase the average kinetic energy of the body without increasing the …
