Document Summary
Matter: is any thing that has mass and takes up space. Chemistry: is the science that deals with matter (structure and properties of matter and transformations from one form of matter to another. Chemical change (chemical reaction): when the substances are used up (disappear) and others are formed to take their place (for example: burning a paper or cooking an egg). Physical change: when the identities of the substances do not change (for example: evaporation of water or melting an ice cream). Chemical properties: when we talk about the chemical properties of a substance, we mean the chemical reactions that it undergoes. Therefore, chemical properties refer to ability of substances to form new substances. Physical properties: these are the properties that do not involve chemical reactions. Typical physical properties of a substance include odor, color, volume, state (gas, liquid, or solid), density, melting point, and boiling point. They expand to fill whatever container they are put into.
