Example 1

easy
Define a physical property and list four examples.

Solution

  1. 1
    A physical property is a characteristic of a substance that can be observed or measured without changing the substance's chemical identity.
  2. 2
    Examples include color, melting point, boiling point, and density.
  3. 3
    Observing these properties does not produce a new substance — the original substance remains unchanged.

Answer

Physical properties: color, melting point, boiling point, density\text{Physical properties: color, melting point, boiling point, density}
Physical properties are observed without altering the composition of the substance. They are useful for identifying and classifying matter without performing chemical reactions.
