Is using a tea bag an example of filtration?

Here's why:

* Filtration: A process where solids are separated from liquids or gases by passing the mixture through a filter. The filter has pores (holes) that are small enough to trap the solid particles, while allowing the liquid or gas to pass through.

* Tea bag: The tea bag acts as the filter. The tea leaves (solid) are contained within the bag, and hot water (liquid) is poured over it. The filter paper in the tea bag traps the tea leaves, allowing the hot water to pass through and extract the tea's flavor.

So, the tea bag effectively separates the solid tea leaves from the liquid tea, which is the essence of filtration.
