* Solution: A solution is a homogeneous mixture where one substance (the solute) is dissolved completely into another (the solvent). The resulting solution has a uniform composition throughout.

* Mixture: A mixture is a combination of two or more substances where each substance retains its individual properties.

In the case of hot tea:

* Tea leaves: The tea leaves are not completely dissolved in the water. You can see the tea leaves or particles in the water, and they retain their properties.

* Water: The water acts as the solvent.

* Other components: The tea also contains other substances like sugar, milk, or lemon, which are also not completely dissolved.

Because the components of hot tea retain their individual properties and are not completely dissolved, it is considered a mixture, specifically a heterogeneous mixture because its components are not evenly distributed throughout.
