What term describes a combination of two or more substances in which each substance keeps its own properties?

• A. Temperature
• B. Mixture
• C. Solution
• D. Energy

Answer: (B)

A mixture is when two or more substances are combined but keep their own properties. In a mixture, each component retains characteristics like color, boiling point, and density, and you can often separate them by physical methods (like picking apart, filtering, or evaporating the liquid). That’s exactly what the description is getting at: the substances mix together without forming new chemical bonds, so they stay identifiable.

In contrast, a solution is a type of mixture where one substance dissolves into another at the molecular level, so you can’t easily see the original parts and their properties aren’t observed separately. Temperature or energy aren’t the right terms for describing how substances combine, so they don’t fit the situation.
