  17. MC for 500 • Magnetism and malleability are physical properties of matter. What makes these properties different from chemical properties? • a. There are no differences • b. physical properties appear only AFTER a chemical change • c. Physical properties can be observed without attempting to change the identity of the substance • C.Physical properties can be observed without attempting to change the identity of the substance
