Question

to identify minerals, scientists look at their properties. properties are attributes or traits that are shared by all members of a group. some properties are chemical and some are physical. unlike chemical properties, physical properties can be measured and observed without changing a substances composition, or what its made of. there are a lot of physical properties. some examples include density, conductivity and magnetism. minerals can be described and identified by their physical properties. some of the properties we use to describe minerals include color, luster, hardness, streak, cleavage and fracture.
which of the following is not an example of a physical property?
choose one option
a flammability
b density
c streak
d magnetism

Explanation:

• Density: It is a physical property as it can be measured without changing the substance's composition.
• Streak: It is a physical property used to identify minerals.
• Magnetism: It is a physical property that can be observed without altering the substance.
• Flammability: It is a chemical property because it involves a substance reacting (burning) and changing its composition.

Answer:

A. flammability
