How does heat transfer in an iron rod?

Question

anyone who's good in science pls help me...

Answer 1

Heat transfer occurs by a property called conduction. For easy understanding let me explain it this way. 20 people stand in line. If i give you a ball and tell you to pass it on, you pass it to the person next to you and he passes it to the person next to him and it continues till it reaches the last person. Same with conduction. Here things happen at a molecular level.

Answer 2

it depend on what and where the heat sourse is. if it is touching by conduction then heat is transfer directly throught the atom to the rod. If it is in a distance but in a closed area it can be done by convection where heat is transfered to the air and then the rod. Or if the source is radiatin heat by radiation where heat waves or somekind of radiation hit the rod exciting the atoms and causing frictino and ulitmatly heating the rod

Answer 3

According to my Phy 108 book, it would travel through conduction, which is the process whereby heat is transferred directly through a material. with any bulk motion of the material playing no role in the transfer. The atoms or molecules in a hotter part of the material will vibrate or move with greater energy than those in the cooler part. By collision, the more energetic molecules pass some energy onto the lesser energetic molecules.

Answer 4

Iron is a good conductor of heat. This is why the iron road becomes hot since the heat passes through it. Wood is a bad conductor of heat. Hence the heat does not pass through the wood.

Answer 5

Well, the electrons *pass on* energy. That's basically what happens, because iron is a good conductor of energy, this is easily done.

Answer 6

By conduction (as opposed to convection or radiation)

Answer 7

its called convection i think
