Question

which option is an example of a physical property?
○ ph
○ boiling point
○ rusting ability
○ toxicity

Explanation:

A physical property can be observed or measured without changing the substance's chemical identity. Boiling point is a physical property as it is the temperature at which a substance changes from a liquid to a gas without altering its chemical composition. pH measures acidity or basicity and involves chemical reactions, rusting ability is related to a chemical reaction (oxidation), and toxicity is related to a substance's ability to cause harm through chemical interactions.

Answer:

boiling point
