To determine which statement is correct about Katie's experiments, we need to understand the difference between physical and chemical properties.

Physical properties are properties that can be observed or measured without changing the substance's chemical identity. Common physical properties include melting point, boiling point, color, density, and solubility.

Chemical properties involve the substance's ability to undergo chemical changes or reactions. Examples include reactivity with acids, flammability, and the ability to rust.

Without the specific details of the experiments listed in the chart, we can't definitively determine which option is correct. However, if Katie's experiments included actions that would change the identity of the substance (like reacting it with an acid), those would indicate chemical properties. If the experiments involved measuring its state, mass, or volume without altering it chemically, they would signify physical properties.

If you can provide me with the specific details of Katie's experiments from the chart, I would be happy to help identify the correct statement!
