Sagot :

Final answer:

Gold is not a good insulator due to its high thermal and electrical conductivity, contrasting with rubber, wood, and plastic that are good insulators.


Explanation:

Gold is not a good insulator as it is an excellent conductor of heat and electricity due to its high thermal and electrical conductivity. On the other hand, rubber, wood, and plastic are poor conductors, making them effective insulators. Insulators like rubber, wood, and plastic do not allow heat or electricity to pass through easily, unlike conductors.
