Physical PropertiesCharacteristics of a substance that can be observed without changing the substance
Examples: color, shape, mass, length, and odor

Chemical Properties
Characteristics of a substance that indicates how it will react with other substances (“the ability to…”)
The original substance is changed in observing a chemical property
Examples: flammability, combustibility, neutralization, and ‘reactions’

Physical Changes
A change where the original substance still exists
The substance only changes form
Examples: cut, dissolved, absorbed, a phase changeClick next slide to play video

Chemical Changes A change where a new substance is produced; the atoms
have been rearranged
When you can’t get the original substance back
Properties of the new substance will be different

Chemical ChangesEasily identified by
the term ‘reacts’ Other ‘clues’:Release of a gasChange in colorRelease of
energy (heat, light, etc.)
Formation of a precipitate

Law of Conservation of Mass
Changes in state does not change the number of molecules in the substance or mixture
100 g of ice = 100 g of water = 100 g of water vapor
