Is tea and ice a homogenerous or pure substance?

* Heterogeneous Mixture: A mixture where the components are not evenly distributed and can be easily distinguished.

* Homogeneous Mixture: A mixture where the components are evenly distributed and appear uniform throughout.

* Pure Substance: A substance that contains only one type of molecule or atom.

In tea with ice:

* Tea: A complex mixture of water, dissolved compounds (like caffeine), and suspended particles (like tea leaves).

* Ice: Frozen water, a pure substance.

The ice and tea are clearly distinct, and the tea itself is not uniformly distributed. Therefore, it's a heterogeneous mixture.
