Physical and Chemical Properties and Changes Review

A student is asked to conduct an investigation to explore properties of matter. Which procedure BEST measures a physical property of the sample?

• experiment: Place the sample in water. results: The sample floats.

• experiment: Place the sample in water. results: The water begins to fizz.

• experiment: Place the sample in water. results: It catches on fire.

• experiment: Place the sample in water for an extended period of time. results: The sample changes color.

Silver is a white metal that is an excellent conductor. Silver tarnishes when exposed to air and light. The density of silver is 10.49 g/cm3. The melting point is 962oC and the boiling point is 2000oC. A chemical property of silver is…..

• that it is a conductor

• its density

• its melting point

• that it tarnishes in air
