BartSMP [9]

Not sure what you are asking. I have two possible answers though...

It could either be more negatively charged, or valence electrons.

The more away from the nucleus a electron is, the more negatively charged it is.

The electrons on the outermost electron shell is valence electrons.

Again, I don't know what you were asking, but one of these answers may be correct.

Two iron rods are placed horizontally, touching end-to-end. One end of one rod is heated. After some time, the other rod also fe
Genrish500 [490]

Answer:

Electrons conducted heat

Explanation:

Iron is a metallic compound. One property of metallic compounds are that they have many loose electrons.

Consider the two rods to be a singular rod, since they touch:

An uncountable number of electrons at one end of the rod are heated, so they gain kinetic energy. Those electrons then collide with other electrons, which energize those as well (although less), which is equal to adding heat. This is a pattern that will flow all the way through the rod.

A battery produces ____current, which is current that flows in only one direction.
fenix001 [56]

Answer:

The given blank can be filled with direct.

Explanation:

A battery refers to a chemical apparatus that is used to store electrical energy. A battery generates a direct current that is a current, which flows in only one direction. DC means direct current and it should exhibit fixed terminals, that is, negative and positive terminals, which cannot be altered.  

As the batteries have fixed content, they possess fixed terminals, thus, they can store only direct current. Thus, the batteries produce direct current and produce a voltage in only one direction, and they exhibit a polarity of negative and positive.
