How does an impurity affect the melting point

WebApr 25, 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). WebApr 11, 2024 · Charcoal can also absorb impurities from the metal, leading to a lower melting point. In addition, charcoal can help to disperse heat more evenly, allowing the metal to melt more quickly. While charcoal is not the only factor that affects melting points, it can have a significant impact on the melting point of certain metals.
