1. Thermal Energy & Heat Transfer
Advanced Physical Science

2. Kinetic Energy Energy of ________________ KE = _________________
Pretend you are a particle and jump around
The more you jump around…the more _______ you have
All matter contains _________that are ___________all the time
Absolute zero=when matter ______ _______ (never been reached)

3. Temperature
Temperature is the measure of the ______ _______ energy of the particles in an object.
The gas particles on the right have a _______ KE than those on the left (therefore higher ______________)

4. Temperature (con’t)
Temperature does NOT depend on how much _________you have
The contents of the teapot and the coffee cup are at the same temperature

5. Thermal Energy
Definition: The _______ ________ _________ of all the particles that make up the object
More _______ = More total Kinetic Energy or…
The more _________ present, the greater the thermal energy
Ex: there is more thermal energy in the ______ than the _______
Also, the higher the ___________
the higher the thermal energy

6. Heat
Definition: The energy ___________ between objects that are at _________temperatures (different Ave ______ _______).
Energy is transferred from _______ (warmer) molecules to ________ (cooler) molecules
Occurs through __________ between molecules
________ MOVES!! (not ______)
___________ is what causes something to FEEL hot or cold
Ex: A doctor’s stethoscope on your back…your body heat is moving to the stethoscope.

7. Heat Transfer-3 types
________

8. Heat Transfer - Conduction
Conduction- transfer of energy through matter by the _____ _______ of particles
When objects that have different temperatures come into contact, energy passes from ______ to _________object until both have same _____________.
Occurs because _______ are in constant _____
KE _______as particles _________

9. Heat Transfer – Conduction (cont)
Conduction can also occur _________an object such as the spoon (below). The part of the spoon in the soup is __________ than the edge.
Conduction works best in _________- especially _________- because particles are close together
_________- good conductors-because ________ move easily & transfer ________ __________ to nearby particles

10. Heat Transfer - Convection
Convection- transfer of thermal energy by the ___________ (or ___________) of a fluid
Fluid- any material that ___________ (can be ________ or _________)
Convection currents transfer heat from ____________ to __________ parts of a ____________________

11. Conduction and Convection
Convection vs. Conduction-
Conduction involves _________ and transfers of energy.
Convection involves _________ of the energetic particles from one __________ to another
Conduction and convection can occur only when ____________ is present.

12. Heat Transfer - Radiation
Radiation is heat transfer through _________ as ____________ _____________.
Does not require a ___________

13. Heat Transfer-summary of all types
Conduction, Convection, and Radiation can occur in the same situation
