Question

Physical and chemical properties of matter​

Answer 1

Explanation:

• A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance.
• Physical properties include color, density, hardness, and melting and boiling points.
• A chemical property describes the ability of a substance to undergo a specific chemical change.

Answer 2

Chemical properties are properties that can be measured or observed only when matterundergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

Physical properties are typically things you can detect with your senses. Examples of physical properties of matter include melting point, color, hardness, state of matter, odor, and boiling point.
