Answer:
a) are close together and can easily transfer energy
Step-by-step explanation:
Note that:
• Molecules of a solid are strongly attached to each other and are tightly bound
,
• The electrons of the solids are delocalized, and are able to move freely
,
• The presence of the free moving electrons due to closeness of the molecules is responsible for the good conduction of solids
Most solids are good conductors of energy because their molecules are close together and can easily transfer energy
