Flow of heat throug the metal stick

Flow of heat is the process in which energy (thermal energy) is transferred from one object to another. Generally, the heat is transferred from the hotter object to the colder object. Temperature determines the direction of the heat flow.

Example

Take a rod or flat strip of a metal, say of aluminium or iron. Fix a few small wax pieces on the rod. These pieces should be at nearly equal distances. Clamp the rod to a stand. If you do not find a stand, you can put one end of the rod in between bricks. Now, heat the other end of the rod and observe. What happens to the wax pieces? Do these pieces begin to fall? Which piece falls first? Do you think that heat is transferred from the end nearest to the flame to the other end? The process by which heat is transferred from the hotter end to the colder end of an object is known as conduction. In solids, generally, the minutes. Touch the other end.
