Question

Which of the following is a good conductor of heat? *
1 point
(a) Iron
(b) Steel
(c) Aluminium
(d) All of these​

Answer 1

Answer:

• Copper is a metal and copper has many free electrons in it. Therefore copper is a good conductor of heat.

Explanation:

iron, aluminum, copper, silver,

brass, lead and stainless steel.

Answer 2

Option (D): Iron, Steel, Aluminum are all good conductors of heat.

Explanation:

• Good heat conductors are materials that allow heat to easily travel through them. The maximum thermal conductivity is found in metals such as copper and aluminum, whereas the lowest is found in steel and bronze.
• Metals are excellent conductors.
• The electrons in metals may easily travel about and transport heat from one part to another, which is why they conduct heat so well. Metal atoms are more tightly packed and thus better at transmitting heat vibrations.
• While most non-metallic solids are good insulators, they have extraordinarily high resistance to charge flow through them.

Hence, all three metals: Iron, Steel & Aluminum are heat conducive.
