Physical/ Chemical Changes

What is a… Physical Change Definition: Any change that alters the form or appearance of matter but does NOT change the substance into a new substance

What are… Physical Changes Examples: Freezing, melting, boiling, hardness, texture, shape, flexibility, dissolving, and filtration.

What is a… Chemical Change Definition: Change in matter that produces one or more new substances

What are… Chemical Changes Examples: Combustion, electrolysis, oxidation, tarnishing.

What are… Chemical Changes Clues: Color change, formation of gas, precipitate, change in temperature

What are… The big difference between physical and chemical properties is…. Physical changes do not change into a new substances but chemical changes do produce new substances
