3 forms of Heat Transfer

• Conduction
• Convection
• Radiation

5
Conduction

• Transfer of energy through matter due to direct
  contact of particles.
• Faster moving particles hit slower moving
  particles transferring momentum causing them to
  speed up

6
Convection

• Transfer of energy by the bulk movement of
  particles from one location to another.
• molecules speed up and move apart becoming less
  dense, they rise
• Cool molecules become
• more dense and sink
• Ex Pan on stove

7
Radiation

• Transfer of energy in the form of waves.
• Travel through matter or through nothing

8
Heat Transfer
9
Insulator

• Do not allow heat to move easily through them.
• Ex wood, plastic, air

10
Conductors

• Allow heat to move through them easily
• Ex Metals
