Conduction Ans Convection Flashcards
What is conduction?
The process where vibrating particles transfer energy to neighbouring particles.
What happens to particles being heated?
They vibrate more and collide with each other.
What do collisions between particles cause?
Energy to be transferred between particles’ kinetic energy stores
What is thermal conductivity a measure of?
How quickly energy is transferred through a material in this way.
If a material has a high thermal conductivity what does that mean for the particles?
Energy transfers between their particles quickly
Convection only occurs in?
Liquids and gases
What is a convection current?
When a warmer and less dense region will rise above denser and cooler regions
Conduction occurs in mainly…
Solids
