Chemistry Notes

1. process that releases energy into the surroundings
4. a pure substance made of only one kind of atom, such as carbon.
6. energy of motion
7. substances that are formed during the reaction.
8. the study of the composition, structure, and properties of matter and the changes it undergoes.
10. a measure of the amount of matter.
12. anything with mass that occupies space.
13. depends on the amount of matter in the sample
14. Low Kinetic Energy -particles can move around, but are still close together.

2. depends on the type of matter, not the amount present
3. Very low Kinetic Energy –particles vibrate but can’t move around.
4. is the capacity to do work or transfer heat.
5. Very high Kinetic Energy – particles collide with enough energy to break into charged particles (+/-).
9. beginning substances that start a reaction.
11. High Kinetic Energy – particles can separate and move throughout container.
