Question

how does heat travel in an iron rod when it is heated at one end?

Answer 1

The heat flows from a body at a higher temperature to a body at a lower temperature. There are three ways in which heat can flow from one object to another. These are conduction, convection and radiation. In solids, generally, the heat is transferred by conduction.


in this case too heat is transferred to one end to another and by conduction.

Answer 2

When one end of the metal bar is heated, the atoms which are in the end of the rod which is heated , vibrate more than the atoms at the other end. The vibration spreads along the bar from atom to atom. The whole rod gets heated.
