What happens to the temperature during fractional distillation as different liquids are collected?

During fractional distillation, the temperature increases gradually until it reaches the boiling point of the component that is being separated. Once a liquid reaches its boiling point, it transitions from a liquid to a vapor phase. As this vapor rises through the column, it cools and condenses back into a liquid, where it is then collected.

While the distillation continues, the temperature will stabilize again at the boiling point of the next component as it evaporates. This systematic increase in temperature correlates with the boiling points of the substances being distilled, allowing for a clear separation of different liquids based on their specific boiling points.

Thus, the process of fractional distillation showcases a progressive increase in temperature in relation to the boiling points of the respective liquids.
