Introduction to Chemistry and Matter
Understanding chemistry involves studying the properties of matter and its changes. Matter is anything that occupies space and has mass, composed of vibrating atoms. It includes examples like air, water, books, desks, and people, while non-examples are light, sound, thoughts, and emotions. Physical properties of matter include texture, color, hardness, and state of matter, while chemical properties relate to its ability to change into a different substance through reactions like burning or rusting.

Physical Properties of Matter Characteristic of a substance that can be observed without changing it into another substance.
Texture Smell Taste Color Flexibility Hardness Weight Freezing point Melting point Boiling point Ability to dissolve (solubility) State of Matter (s, l, or g)
Chemical Properties of Matter Characteristic of a substance that describes its ability to change into a different substance
Ability to burn (Flammability) Ability to rust Ability to tarnish Ability to react with other substances (ie: acids)
