Question

classify each of the following as a physical property or as a chemical property. physical property: a characteristic of matter that is observed with the senses and can be determined without changing the identity of the object. chemical property: a characteristic that indicates how a substance reacts with something else. when observed, the original substance is changed into a different substance. physical property chemical property blue color density combustibility boiling point reacts with acid

Explanation:

Blue color can be observed with the eyes without changing the substance's identity, so it's a physical property. Density is a measurable characteristic without altering the substance, thus a physical property. Combustibility involves a substance reacting and changing into different substances when burned, so it's a chemical property. Boiling point is determined without changing the substance's chemical identity, making it a physical property. Reacting with acid changes the original substance into a different one, so it's a chemical property.

Answer:

Blue color: Physical property
Density: Physical property
Combustibility: Chemical property
Boiling point: Physical property
Reacts with acid: Chemical property
