Heat Conduction

Question 1

What is conduction of heat energy?

Answer 1

The process where Vibrating Particles pass on their Extra Kinetic Energy to Neighbouring Particles

Question 2

Conduction of heat energy continues through the solid and gradually some of the [ ] (or heat), passes all the way through the solid, causing a rise in [ ] at the other side of the solid. Hence an [ ] in heat radiating from its surface

Answer 2

extra kinetic energy
temperature
increase

Question 3

Usually conduction is faster in…

Answer 3

…denser solids, because the particles are closer together and so will collide more often and pass energy between them

Question 4

Materials that have [ ] spaces between their particles conduct heat energy much more slowly - these materials are [ ]

Answer 4

Larger

Insulators

Question 5

Why are metals good conductors?

Answer 5

They have FREE ELECTRONS which are free to move inside the metal, therfore heat energy travels really fast through metals

Question 6

At the hot end, the electrons move [ ] and collide with [ ], transferring [ ]. The cycle continues all the way up the metal.

Answer 6

faster
other free electrons
energy
