Explain the key steps involved in fractional distillation. |
The column is hot at the bottom (350°C) and cool at the top (25°C). Substances with high boiling points condense at the bottom, substances with low boiling points condense at the top. Like distillation, fractional distillation works because the different substances have different boiling points |
