Conduction and Convection Flashcards
1
Q
Define conduction
A
The process where vibrating particles pass on their extra kinetic energy to neighbouring particles
2
Q
Usually conduction is faster in…
A
denser solids because the particles are closer togethr and will collide more often and pass energy between them
3
Q
Why are metals good conductors
A
Because they have free electrons that transfer energy
4
Q
Define Convection
A
Convection occurs when the more energetic particles move from the hotter region to the cooler region and take their heat energy with them
5
Q
During convection what happens to a particle that heats up
A
It becomes less dense and rises
