I have got a question about distillation. In distillation as we know the mixture is boiled and the mechanism then goes like substances with high boiling points condense at the bottom and substances with lower boiling points condense on the way to the top. I don't know why, but I am having difficulty understanding that why should a substance with high boiling point go to the bottom and the substance with the low melting point get higher. This goes against my intuition. Basically what I think is that higher boiling point means greater energy to the system and thus higher output in form of reaching higher. However, according to the real observation, I am wrong.
So does the system behave like this? Higher boiling point means that after the system changes into gaseous state (most probably), it radiates energy faster that the substance with the lower melting point.
Is this explanation of the phenomena correct?
If yes then explain why does the substance with higher boiling point radiate energy faster?
If not then please mention the right mechanism .
