Question

which of the following examples depict(s) a physical property?

a \tsugar is white in color

b \tiron is more dense than aluminum

c \tdiamond is harder than graphite

d \tall of the above

Explanation:

A physical property is a characteristic of a substance that can be observed or measured without changing the substance's chemical identity.

• Option a: Color (white of sugar) is a physical property as it can be observed without altering sugar's chemical composition.
• Option b: Density (iron being more dense than aluminum) is a physical property, measurable without chemical change.
• Option c: Hardness (diamond harder than graphite) is a physical property, determined by physical interaction (scratching) without chemical reaction.

Since a, b, and c all represent physical properties, the correct choice is d.

Answer:

d. All of the above
