Heat Transfer Flashcards
(5 cards)
What is conduction?
Increase in kinetic energy of particles from other particles with higher energy levels
What state does conduction work best in?
Solids because particles are closely packed

What is convection?
Particles move along temp. gradient (hot -> cold)
What are the steps for convection?
1) Hot particles move up to cooler particles
2) Hot transfers cold,
3) The now cold particles move down to get hot particles
What state does convection work best in?
Gas and liquid since the particles are more free to move
