energy transfer by conduction Flashcards
1
Q
what are the best conductors of energy
A
the best conductors of energy are metals
2
Q
what are the best insulators of energy
A
the best insulators of energy are non-metal materials such as wool and fibreglass
3
Q
what is thermal conductivity
A
4
Q
how does the thermal conductivity of a material affects the rate of energy transfer through it by conduction
A
The higher the thermal conductivity of a material, the higher the rate of energy transfer through it.
5
Q
what does the energy transfer per second through a layer of insulating material depends on
A
it depends on:
* the temperature difference across the material
* the thickness of the material
* the thermal conductivity of the material.
