Question

Which of the following is not an example of a physical property?

A
flammability

B
density

C
streak

D
magnetism

Answer 1

Answer:

A)flammability

Explanation:

A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

A)Flammability is a chemical property, or one that can be observed when a substance changes into something else

• B)Density is a physical property of matter that expresses a relationship of mass to volume. The more mass an object contains in a given space, the more dense it is. ... Density is also affected by the atomic mass of an element or compound.
• C)Streak is the color of a crushed mineral's powder. The color of a mineral's powder may differ from the actual color of the mineral. This property can be useful for mineral identification.
• D)Magnetism is a physical property because attracting something to a magnet does not change the substance (change of the composition) itself and doesn't involve chemical reactions.

Answer 2

Explanation:

Flammability is not a physical property. It is a chemical change.

Flammability is a chemical property because it can only be observed or measured during a chemical change known as combustion. Combustion is a chemical reaction that occurs when a fuel reacts with oxygen to produce light and heat.
