conduction

Question 1

what is conduction?

Answer 1

the transfer of heat energy through a solid

Question 2

how is the energy transferred by?

Answer 2

by the vibrations of particles

Question 3

what do the particles do when the solid is being heated?

Answer 3

get bigger

Question 4

what are the best conductor of heat energy?

Answer 4

metals

Question 5

why are metals the best conductors ?

Answer 5

because heat is transferred by free electrons that transfer their kinetic energy around the metal by colliding with other free electrons and fixed metal ions.

Question 6

what are non-metals and gasses? and what do they not contain?

Answer 6

usually poor conductors, called insulators they do not contain free electrons

Question 7

what is the process of conduction in non-metals?

Answer 7

if one end is heated, the particles of the solid gain kinetic energy causing them to vibrate more. The process of conduction in non-metals is slow
