Verified step by step guidance1
Understand the definition of a physical property: Physical properties are characteristics of a substance that can be observed or measured without changing the substance's chemical identity.
Review each option to determine if it describes a physical property: A physical property should not involve a change in the chemical composition of the substance.
Analyze the option 'The brittleness of solid sulfur': Brittleness is a physical property as it describes how a material breaks or shatters without changing its chemical structure.
Consider 'The density of iron is 7.87 g/cm^3': Density is a physical property because it is a measure of mass per unit volume and does not involve a chemical change.
Evaluate 'An iron bar rusts': Rusting is a chemical change where iron reacts with oxygen to form iron oxide, thus it is not a physical property.
