Heat Transfer Notes
________________________________________ measures the average ________________________ of the molecules (how fast they are moving…._____________________ = _____________________).
Heat moves from ____________________ to ______________________ until all the objects are the ___________________________ temperature.
Anything with molecules has _____________________ energy.
_______________ ________________ makes molecules move!
More heat = molecules move ____________________________
Less heat = molecules move _____________________________
Heat Transfer – Heat can move in _______________________ way.

Thermal energy transfer is ____________________ moving from a ________________ object to a _________________ object.
Conduction
___________________________ is heat is transferred from one object to another object through ___________________ _____________________
Conduction = _____________________
_____________________ to Solids.
List two examples of conduction:
1) _________________________________________________
2) _________________________________________________
Draw a picture of conduction taking place.
Convection
______________________ is heat is transferred by currents within a ________________________ or ___________.
Convection = _____________________ (through air and liquid particles)
Convection happens in _______________ or ________________, not solids.
Convection moves in a _________________ pattern.
List two examples of convection:
1) _________________________________________________
2) _________________________________________________
Draw a picture of convection taking place.
Radiation
________________________ is the transferred of energy by electromagnetic ________________ through _________________.
Radiation does ___________________ require matter to ___________________ thermal energy.
Radiation = __________________________ (heat escaping the sun)
List two examples of radiation:
1) _________________________________________________
2) _________________________________________________
Draw a picture of radiation taking place.
