1 Matter: Properties and Change

2 Matter Anything that takes up space and has mass

3 Law of Conservation of Matter Matter can not be created or destroyed These legos weigh the same when they are together and taken apart

4 qualitative Information collected and communicated in words Observable by using your senses Example: color, shape, odor

5 quantitative Exact information about the quality you observe using numbers rather than words. Example: length, weight, volume, temperature

6

7 weight Measure of the pull of gravity on an object

8 States of Matter Solid-definite volume; doesn’t change Liquid-a definite volume but no shape Gas- no definite volume or shape Plasma

9

10 Boiling Point – The temperature at which liquid matter experiences the same pressure as the atmospheric pressure; turns to a gas Freezing Point – The temperature at which liquid matter turns to solid.

11 Melting Point – The temperature at which solid matter turns to liquid.

12 Physical Properties of Matter Observable characteristics that can change without changing their chemical composition Example: color, form or shape

13 Physical Change Changes in shape, size or physical state (phase) of matter Example: Shredding paper, cutting up fruit, freezing water, boiling water

14 Chemical Properties of Matter Properties of a substance that when changed, result in a new substance Example: ability to conduct heat; reactivity with other substances (rust) These properties create chemical changes in a substance

15 Chemical Change A change in matter that produces new substances Examples: Ability to burn Wood to ash Ability to rust/ react with oxygen Metal to rust Ability to form a new substance with chemical composition different than the original substance. Digestion of food
