which of the following substances would most likely be
used for the heating elements in a toaster and why?
select an answer
wood because it is a conductor and a nonmetal.
copper because it is an insulator and a metal.
wood because it is an insulator and a nonmetal.
copper because it is a conductor and a metal.

Explanation:

Heating elements in a toaster need to conduct electricity to generate heat. Metals are good conductors of electricity. Copper is a metal and a conductor. Wood is a non - metal and an insulator (does not conduct electricity well). So, the correct reasoning is based on conductivity and the nature (metal/non - metal) of the substance.

Answer:

Copper because it is a conductor and a metal.
