Absolute Zero
All molecular movement ceases- it is the lack of any energy
Lowest possible temperature ever- only theoretical
-459°F or -273°C or 0 kelvin

8. Closed system- Energy can not escape or enter
Page 1
Conservation of Energy- Energy can not be created nor destroyed, but transformed from one type to another
Closed system- Energy can not escape or enter

9. ENERGY ALWAYS FLOWS FROM HIGH  LOW or SOURCE TO SINK

Source-
Sink-
ENERGY ALWAYS FLOWS FROM
HIGH  LOW or SOURCE TO SINK
Ex: Sun to Earth
Where it comes from
Where it flows (goes)

12. Energy Transfer from Sun

Energy Transfer from Sun
Electromagnetic energy is a type of energy that is radiated by the sun in the form of transverse waves

13. Electromagnetic Energy
Page 2
ALL OBJECTS THAT HAVE A TEMPERATURE GREATER THAN ABSOLUTE ZERO EMIT (GIVE OFF) ELECTROMAGNETIC ENERGY
***Higher temperature more radiated energy***
amplitude
***Put this key concept at bottom of page 2***

14. Electromagnetic Energy
Page 2
Transverse Wave- a wave that vibrates at right angles to the direction at which it is traveling

15. Parts of a Transverse Wave
Page 2
Crest- top of a wave
Trough- bottom of a wave
Amplitude- height of a wave

16. Parts of a Transverse Wave
Page 2
Wavelength-is the distance between two successive crests or troughs

17. Page 2
Frequency- is the number of waves
which pass a certain point in a
second
The longer the wavelength,
the lower the frequency 
The shorter the wavelength ,
the higher the frequency 

18. The Electromagnetic Spectrum (EME) is a model of the different forms of radiation
Page 2

19. All types of EME are similar: they travel to you in transverse waves
Page 2
All types of EME are similar:
they travel to you in transverse waves
they travel at the speed of light
are radiated

22. Radiation occurs in different forms identified by their wavelengths

4. Why is the ozone layer important?
b/c they absorb harmful UV radiation
