Question

What are good conductors of heat?

Answer 1

Good conductors of heat:

• Materials that allow heat to pass through them easily are called good conductors of heat.
• The reason metals conduct heat so well is because the electrons in them can move around easily, and they can carry heat from one part to another.
• Metal atoms are packed more densely and can transmit heat vibrations more readily.
• While most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
• Metals like copper and aluminium have the highest thermal conductivity while steel and bronze have the lowest.
• As copper is an excellent conductor of heat, it is good for heat exchangers also.
• Example: Gold, Silver, Iron, etc are some examples of good heat conductors and electrical conductors.

Hence, metals are known as good conductors of heat.
