Yr8-Energy Transfer:Particles Flashcards
What is a conductor?
A conductor is when energy can be transferred quickly
What can conductors lead to?
Conduction
Give the three ways in which energy can be transferred
Conduction, convection and radiation
In conduction, how do they transfer to the other side?
They collide to each other and vibrate
When does energy transfer stop?
Until the 2 surfaces are at the same temperature unless you carry on heating it.
Is wood a good conductor?
No but they are insulators
Give the definition of the insulator
Something that is good at keeping heat but not transferring heat
Are liquids good conductors?
No
Are gases and liquids good conductors?
No because the particles are to spread apart to vibrate
Explain convectional current
The soup in the pan gets hotter and moves each other. They move faster the soup becomes less dense. The hotter soup rises and the cool goes down.
