Question

A physical property is:a) a property the sample displays that results in a change in composition. b) the ability of a sample to undergo change. c) always visible. d) a property the sample displays without changing its composition.

Answer 1

Answer: Option (d) is the correct answer.

Explanation:

Properties that are unable to bring any change in chemical composition of a substance are known as physical properties.

For example, size, shape, volume, density, boiling point, melting point etc is a physical property.  

Whereas properties that bring change in chemical composition of a substance are known as chemical properties.

For example, combustion, toxicity, reactivity etc are all chemical properties.

Thus, we can conclude that a physical property is a property the sample displays without changing its composition.
