Question

which option is an example of a physical property?
ph
flammability
freezing point
toxicity

Explanation:

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

Answer:

freezing point
