Changes in Mass
P.CM.06.12 - Explain how mass is conserved as a substance changes from state to state in a closed system.
Law of Conservation of Mass: The fact that matter cannot be creasted or detroyed in any physical of chemical change.
Physical Property: A characteristic of a pure substance that can be observed without changing it into another substance. Types: Physical state, texture and color, flexibility, etc..
example: Physical state: Above 0 degrees celsius, icicles of solid water will change into a liquid.
Chemical Property: A characteristic of a pure subsance that can be observed by changing it into a different substance.
example: gases produced during baking create spaces in freshly made bread. Iron can form rust, turning a shiny car into a crumbling one!
Physical Change: Any change that alters the form or appearance of matter but does not make any substance in the matter into a different substance. Ex: cutting paper.
Types: Change in state, change in shape or form
Chemical Change: Any change in matter that produces one or more new substances.
Types: Combustion, Electrolysis, Oxidation, Tarnishing
