You have an unknown chemical. What would be the best property to use to identify the chemical?

• volume

• boiling point

• color

• mass

How do you describe physical properties?

• can cause atoms to change structure when mixed

• are observed when seeing how one thing reacts with another

• can be observed without changing the identity of the substance

• behave the same for all matter under the same conditions

What physical property is most like the same for metals?

• low melting point

• high conductivity

• low boiling point

• high magnetism

What would be the LEAST helpful in identifying an unknown sample?

• melting point

• magnetism

• weight

• solubility

An example of a chemical property is

• reactivity

• density

• texture

• color
