Heat Transfer Flashcards
1
Q
What is conduction?
A
Increase in kinetic energy of particles from other particles with higher energy levels
2
Q
What state does conduction work best in?
A
Solids because particles are closely packed

3
Q
What is convection?
A
Particles move along temp. gradient (hot -> cold)
4
Q
What are the steps for convection?
A
1) Hot particles move up to cooler particles
2) Hot transfers cold,
3) The now cold particles move down to get hot particles
5
Q
What state does convection work best in?
A
Gas and liquid since the particles are more free to move
