P2Energy Transfer By Heating Flashcards
1
Q
Which materials make the best conductors?
A
Metals are the best conductors of energy
2
Q
Which materials make the best insulators?
A
Non-metals such as wool and fibreglass are the best insulators
3
Q
How does thermal conductivity of a material affect the rate of energy?
A
The higher the thermal conductivity of a material) the higher the rate of energy transfer through it.
4
Q
How does the thickness of a layer of a material affects the rate of energy transfer by conduction through it
A
The thicker the layer of an insulating material, the lower the rate of energy transfer through it.
