2.1 energy transferred by conduction Flashcards
1
Q
Are metals good conductors of energy?
A
Metals are the best conductors of energy
2
Q
What materials are the best insulators?
A
Non-metal materials such as wood and fibreglass
3
Q
How does the thermal conductivity of material affect the rate of energy transfer?
A
The higher the thermal conductivity of material, the higher the rate of energy transfer through it
4
Q
How does the thickness of an insulating material affect the rate of energy transfer?
A
The thicker layer of insulating material, the lower the rate of energy transfer through it
5
Q
What does thermal conductivity mean?
A
A measure of how quickly energy transfers through it by heating
