1. Conduction
Conduction is Touchin!

2. 1) Measure temperature change, or simply “feel” heat!
2) Some kind of movement. (kinetic energy)

3. 3) Spoon got hotter from the “bottom” end to the “top” end.
4) STRAIGHT LINE – from one end to the other!

4. 5)

5. 6) Transfer of heat in a straight line path due to direct contact between one medium (substance) and another.
* 2 materials at different temps.
* particles warm up, move faster, and bump into the next particle…..CLOSER THE BETTER

6. 7) Would be the same except much slower in a liquid (less heat transfer) and really slow in a gas.

7. 8) Thermal Conductor = good at transferring heat
Ex: metals, glass, water??
Thermal Insulator = do not transfer heat
Ex: wood, plastic, air, styrofoam
