Can a chemist help identify a substance by its physical properties?

Can a chemist help identify a substance by its physical properties?

Hardness, color and boiling point are physical properties because they can all be observed and/or measured without manipulating the composition of the substance.) Physical properties can help a chemist identify a substance.

Can physical properties identify a substance?

Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties are known as intensive properties and are used to identify a substance.

How are physical properties helpful to chemists?

How to proceed scientifically when studying the properties of an unknown liquid?

To proceed scientifically, you could measure several properties of the unknown liquid and compare them with the properties of known substances. You might observe and measure such properties as color, odor, texture, density, boiling point, and freezing point.

What is observed only when a substance undergoes a chemical change?

Chemical properties are observed only when a substance undergoes a chemical change. What happens during a chemical reaction? Circle the letter of the term that best completes the sentence.
