Chemical Property.

Chemical Property.

• A. A property that describes color
• B. Something that changes to a new substance
• C. A property that describes mass
• D. A property that describes temperature

Answer: (B)

A chemical property describes how a substance behaves in a chemical reaction and whether it can form a new substance. It’s about what the substance can do when it interacts with something else or energy, not just how it looks or feels. The option that says it changes to a new substance fits this idea, because it highlights the outcome of a chemical change—the formation of a different substance. In contrast, color, mass, and temperature are physical properties; they can be observed without altering the substance. Color describes appearance, mass describes how much matter, and temperature describes how hot or cold it is. These don’t involve forming something new. So the concept being tested is that a chemical property relates to the ability to turn into a different substance.
