Explain in 2-4 sentences, in your own words, what makes a pure substance different from a mixture.

Answer 1

A pure substance consists of a single type of material with a uniform composition and distinct properties, such as boiling and melting points. In contrast, a mixture contains two or more different substances that can be separated by physical means and may vary in composition and characteristics. While pure substances have consistent properties, mixtures maintain the individual characteristics of their components.
