Hot Metal ended on 1989-03-10.
When one end of a metal is heated, the particles at that end begin to vibrate more rapidly, transferring kinetic energy to neighboring particles along the metal. This causes the metal to conduct heat from the hot end to the cooler end, resulting in the temperature of the entire metal eventually equalizing.
You have to get it hot enough where you get to the melting point of the metal. During this melting process the impurities will be removed from the metal and your end result is a purer metal.
Yes, particles at the hot end of a metal rod vibrate faster than those at the cold end due to the increase in thermal energy. This increase in vibration causes the particles to collide more frequently and transfer heat along the rod through conduction.
This example illustrates the process of heat transfer through conduction, where heat is transferred from the fire through the metal bar to Jimmy's hand. The metal bar acts as a conductor of heat, allowing the energy to flow from the hot end to the cooler end.
You can draw a diagram showing how heat is transferred through a solid material, such as metal, from a hot end to a cold end. Label the hot end with a flame or heat source, the cold end with a snowflake or refrigerator, and arrows to indicate the direction of heat flow.

Hot Metal Bridge was created in 1887.
Hot Metal was created on 1986-02-16.
Metals generally exhibit good thermal conductivity. When one end of the metal rod is held in the flame it absorbs thermal energy and becomes hot. Thermal energy is conducted quickly along the material (from hotter to cooler parts of the rod), and the other end eventually becomes hot. This principal is used in cooling systems for electronics (for example) with heat sinks drawing thermal energy away from hot components in order to radiate it elsewhere.
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.
