Q125
Metals are good conductors of heat because
A.
Their atoms collide frequently
AnswerB.
Their atoms are relatively far apart
C.
They contain free electrons
D.
They have high density
Answer: Option A
Solution
Answer: Option A
Solution:
Metals are particularly good conductors of heat because their particles are very closely packed so the vibrations are passed on very quickly. These drift slowly through the structure, giving metals their strength and other properties.
As the metal is heated, the free electrons closest to the heat source are heated.
