Lesson 2 - Heat Transfer Flashcards
1
Q
How is heat energy transferred by conduction
A
It is the passing of heat by vibrations from particle to particle without the object itself moving
2
Q
Why are solids good conductors
A
It only occurs in solids and the particles are closer together
3
Q
Why is wood not a good conductor as metal
A
Metals (e.g. copper and iron) are better conductors than non metals (e.g. wood and plastic) Wood has no free electrons to pass the vibrations
