Which term describes a mix of different elements?

The term that describes a mix of different elements is "heterogeneous." This term specifically refers to a system or mixture that contains components that are not uniform in composition or character, meaning that the individual elements can be distinguished from one another. In a heterogeneous mixture, you will find various substances that maintain their distinct properties, such as having different textures, colors, or phases.

For example, a salad is considered a heterogeneous mixture because you can see and separate its ingredients, like lettuce, tomatoes, and cucumbers, which do not blend into a single uniform substance. Understanding this concept is crucial as it relates to various fields, including chemistry and materials science, where distinguishing between different types of mixtures is necessary for effective analysis and application.
