Schrdinger Model

1
Schrödinger Model

• Nothing need for this class more than Bohr model
• Key difference - Bohr has atoms like solar
  system Schrödinger says not in circles but
  probability levels
• Both have different energy levels

2
Changes of State

• What state atoms are in tells us what
  temperatures stars are - they have different
  spectral signatures
• Know states from cold to hot

3
Tyypes of Spectra

• Important to know which kind each is from
• Blackbody - Continous spectrum
• Excited gas - electrons changing levels -
  Emission Line Spectrum
• Seen through gas - Absorption Line Spectrum

4
Savage Sun, Pt 2

• Heavy water - Hydrogen has Proton, Neutron, 7
  Electron
• Regular Hydrogen has no neutron

5
Questions

• add proton pos charge add Neutron isotope
• Su's energy is Fusion
• Sun most like nuclear bomb, though could argue
  others
• dif pro neut proton is positive neutron is
  neutral

6
Cored Picture

• Core
• Radiotive zone
• Copnvective zone
• Photosphere

7

• How big 100x
• volume is diameter cubed so much larger volume
• interior is not low density gas
• St
• Bal
• Gravitational forces make it shrink
• Doesn't shrink in the core because of nuclear
  repulsion

8
Power

• P
• energy is how much ability to do things
• Power is how much energy and how much time
• example was lifting ruler - lift slow or fast
  uses same energy but more power for faster
• power is measured in watts
• A
• T
• O

9
What Max Pwr on earth surf

• _at_ 1,000

10

• A
• A
• Solar cells - efficiency
• Not many at 50

11
What Photon

• Packet energy
• KNOW

12
Which Hotter

• interior sun hotter
• inter earth is _at_ same as SURFACE of sun

13
Structure

• P
• B
• a lot of energy is produced in core emits light
  but it is absorbed reemmited
• pic - temp densty c omarison from center to
  surface
• Sun is both larger more dense at center

14
Thermal Energy Transfer

• C
• example pot of water
• bottom is where in contact with heat
• heat naturally rises - less dense than cold
  particles
• Process in interior of earth responsible for
  motion of plates / mtns / continits
• liquid state
• C
• hot touching cold will transfer thermal energy
  until temp equalizes
• usually one object - solid state
• R
• blackbody gives off radiation
• radiation interacts with objects - it heats up -
  does not have to be touching
• Pic of pot bar

15
How toast heat

• c
• not same so does not rotate
• c
• if in skillet
• R
• Heat radiatios off elements
• Example also heating lamp

16
Why cold in lake

• C
• because no conv is why warm water is at top -
  heat source is sun
• C
• water pulls heat off skin through contact
• R

17
Energy Transport

• pic cut away sin
• core creates energy
• raditaticve zone - heat transfer from radiation
• convection - heat moves out at surface so gets
  cooler rotates

18
Pressure

• F
• F
• CORRECT
• Force divided by how big of an area it acts on
• Force Pressure is not interchangeable
• A
• F

19
Pic sun cross sect

• Sun nor earth atmosphere not collapse - why

20
Pic box of atmosphere

• atmosphere has mall which pushes down
• ar above pushes down
• air below pushes up
• upward force has to be equal to what pushing down
  in static model
• actually pushes up more than down so equals down
  plus weight
