What separation method is used for hot water and tea leaves?

The separation method used for hot water and tea leaves is filtration. Filtration is a mechanical separation technique used to separate solid particles from a liquid by passing the mixture through a filter. The filter allows the liquid to pass through while retaining the solid particles.

In the case of hot water and tea leaves, a tea infuser or a tea bag can be used as a filter. When hot water is poured over the tea leaves, the water dissolves the soluble substances in the tea leaves, such as caffeine, tannins, and flavor compounds. The insoluble substances, such as tea leaves and other plant matter, are retained by the filter. The resulting liquid is called tea.
