Question

A physical property is a characteristic of a substance that can be observed and measured without changing the identity of the substance.

Which of the following would be considered a physical property? (Select all that apply)

1. density
2. states of matter
3. electrical conductivity
4. flammability

Answer 1

Density, states of matter, and electrical conductivity are physical properties because they can be observed or measured without changing the substance's identity, while flammability is a chemical property.

Step-by-step explanation:

Physical properties are characteristics of a substance that can be observed or measured without altering the substance's chemical identity. Among the options provided, the physical properties are density, states of matter (solid, liquid, gas), and electrical conductivity. These can all be observed or measured without changing the identity of the substance in question. Flammability, however, is not a physical property but a chemical property since it describes the substance's ability to undergo a chemical change, specifically combustion.
