Understand the difference between physical and chemical properties: Physical properties can be observed or measured without changing the substance's identity, while chemical properties describe how a substance reacts with other substances.
Review each option and determine if it involves a change in the chemical identity of oxygen or not.
For example, 'Oxygen forms oxides with metals' involves a chemical reaction forming new compounds, so it is a chemical property.
'Oxygen supports combustion' describes oxygen's role in a chemical process, so it is also a chemical property.
The statement 'Oxygen is colorless and odorless at room temperature' describes characteristics that can be observed without changing oxygen's chemical identity, making it a physical property.
