When a metal rod is heated at one end why does the other end become hot?

# Hot. # Longer. # Larger diameter. # More resistive to current flow. # The speed of sound in the metal increases. # Its strength decreases.

∙ 15y agoThis must be by perception of contrast. I can't see that a heated rod gets hotter once the source of heat has been withdrawn.

∙ 13y agobecause heat makes steel more flexible where atoms take more energy that absorbed by electrons to move a molecules of rod to have a larger mass and more length.

∙ 12y agoMetal is a conductor of heat. Heat can pass through it easily. So when heat is applied to oneside it travels to the other.

How does heat travel along a metal?
By conduction. This means that atoms of the metal become more energetic when heated, and they transfer this energy from atom to atom, so it travels along the bar from the hot end to the cooler end
When a metal rod is heated at one end what energy transfer takes place in the rod?
conduction
How heat transfer by conduction?
the particles at the heated end in say a metal rod gain kinetic energy and therefore start to vibrate more. These heated particles then hit other less energetic (hot) particles and then the heat is passed on that way until the whole object is heated up.
Can you generate electricity from hot metal body?
If two metals are joined to form a thermocouple, then when their junction is heated, electrons will flow away from the junction - a tiny electrical flow. When a metal is heated, electrons will flow away from the hot end of the metal. Once again a tiny amount.
What is a material that conducts thermal energy?
If you want an example: Any metalIf you want an explanation:It is a material that allows heat to pass through it. If you heat up the end of metal rod the other end will become hot shortly afterwards because the metal conducts heat down it.
When a metal rod is heated at one end which end is hotter?
The end that is being heated should be hotter than the other end.
What happens when one end of a metal slab is heated and ice is placed on the other end?
Heat will be transferred through the metal and begin melting the ice at the other end. Metal is a very good conductor of heat and heat like most other things prefers to equalize itself if possible.

When one end of a piece of metal is heated what happens?
the partcles get closer together or the particles get bigger. you decide
What happens to the particles in a metal when the metal is heated?
When a metal bar is heated....the particles in the area of the metal bar that is hot start vibrating.. knocking into each other and passing the heat energy on to cooler particles. The cooler end that isn't heated still has a rise in temperature just not as much as the heated area because the heat has almost been diluted.

How did ranchers know their cattle?
they branded their cattle (they heated a metal rod with a specific symbol at the end and burned it into their skin).

What happens if a metal rod is heated at one end?
The drawing pin which is the closest to the heat/bunsen burner will fall off first because of the heat partials travel through the metal rod and through each piece of wax causing the wax to melt.

WHY is metal a good condutor of heat?
it is because of the mobile electron pool. due to this electron arrangement metal ions are so closely packed, when one end is heated the ions in that end vibrate.this results the neighbouring ions to vibrate one by one. thus thru vibration heat is carried from one end to the other. since such an arrangement is found only in metals,metals are good thermal conductors..
