Answer: The given statement is true.
Explanation:
A property that does not bring any change in chemical composition of a substance are known as physical properties.
For example, shape, size, mass, volume, density, etc of a substance are all physical properties.
As melting of ice only changes its state and not its identity.
And, a property that changes chemical composition of a substance is known as chemical property.
For example, precipitation, reactivity, toxicity etc are chemical property.
Therefore, we can conclude that the statement a characteristic of a substance that can be observed or measured without changing the identity of the substance is a physical property, is true.
