1. combustion – rapid combination of fuel with oxygen
Gas, oil, or coal burning
2. Electrolysis- use of electricity
Breaking down water into H and O2
3. Oxidation – combination of a substance with O2
Rust
4. Tarnishing- slow combination of bright metal turning dull

TEMPERATURE – is a measure of how hot or cold something is

24. https://youtu.be/EBcp24-wJW4
The hotter an object is, the faster the motion of the molecules inside it.

25.
Thermal Energy- is the total energy of the motion of all of the particles in an object.
Ther mal ener gy- is the total ener gy of the motio n of all of the parti cles in an objec t.

26. Endothermic vs exothermic
Ther mal ener gy- is the total ener gy of the motio n of all of the parti cles in an objec t.
Endothermic vs exothermic

27. Endothermic- absorbs energy

28. Exothermic- releases energy
