Is soup a pure substance or mixture?

* Pure substances have a fixed composition and cannot be separated by physical means. Examples include water (H2O) or table salt (NaCl).

* Mixtures combine two or more substances that are not chemically bonded. They can be separated by physical means.

Soup contains many different ingredients like vegetables, broth, spices, and possibly meat or noodles. These ingredients are not chemically combined, and you could separate them using methods like filtration or evaporation.

Therefore, soup is a mixture, specifically a heterogeneous mixture, as its components are not evenly distributed throughout.
