Why can heat not be transferred in this way with an iron rod?
Heat cannot be transferred in this way with an iron rod because iron is a good conductor of heat. When the iron rod is held at one end and heat is applied to the other end, the heat energy will quickly travel through the iron rod, leading to a uniform temperature distribution along the rod.
Is iron rod a conductor or insultator?
It is an electrical conductor, because it is made of iron. Iron, like all metals, contains "free" or "conduction" electrons which can move through the metal and carry charge. Iron is also a thermal conductor, for the same reason.
Is rod conductor or insulator?
A rod can be either a conductor or an insulator, depending on its material properties. For example, a metal rod would act as a conductor, allowing electricity to flow through it easily. In contrast, a wooden rod would be an insulator, preventing the flow of electricity.
How do you prove that iron is good conductor of heat?
Iron is a good conductor of heat because its electrons are free to move and carry thermal energy throughout the material. This allows the heat to easily flow through the iron, making it an efficient conductor of thermal energy. Additionally, experiments that measure the rate at which heat passes through iron compared to other materials can provide evidence of its good thermal conductivity.
Can electricity pass through copper rod?
Yes, electricity can pass through a copper rod as copper is a good conductor of electricity due to its high conductivity properties. The electrons in a copper rod are able to move freely, allowing electricity to flow through it easily.

After wrapping a thin paper strip tightly around an iron rod then holding over a candle while rotating the iron rod continuously does the paper burn?
Iron rod is the good conductor of heat first of all it receives heat and after sometime paper gets heated and catches fire

Is a rod a good conductor of electricity?
if it is made of metal.
Wrap a thin paper strip tightly around an iron rod . try to burn the paper with candle while rotating the iron rod continuously . does it burn .explain your observation?
If you introduce the rod with the round strips into the flame of a candle, the paper will not catch fire. The fire will lick the paper but not burn down until the iron rod becomes hot. This is because iron rod just like any other metal is a good conductor of heat, it leads away the heat obtained by paper from the candle flames. Replace the iron rod by a wooden stick and paper will burn because wood is a poor conductor of heat. With copper rod the experiment is more successful.

Why copper rod is covered with insulating material in Searle's apparatus?
Copper rod is covered by insulating materials, because copper is good conductor of electricity when we touch copper rod we get shock and insulators are bad conductor of electricity hence copper rod is covered by insulating materials

Yes, electricity can pass through a copper rod as copper is a good conductor of electricity due to its high conductivity properties. The electrons in a copper rod are able to move freely, allowing electricity to flow through it easily.
What happens when an iron rod is rubbed with silk?
When an iron rod is rubbed with silk, electrons move from the silk to the iron rod, resulting in the iron rod becoming negatively charged and the silk becoming positively charged. This creates static electricity on both the iron rod and the silk.
How does the iron rod heat up?
When an iron rod is subjected to heat energy, the atoms within the rod start vibrating more rapidly, which results in an increase in temperature. This increased vibration causes the rod to heat up as the kinetic energy of the atoms is converted into thermal energy.
Why does a metal rod feels colder to touch than a wooden rod at the surrounding temperature?
Metal is an excellent conductor of heat. The moment you grasp the metal rod, the heat of your hand is conducted away rapidly by the dense metal. If feels "chilly". Wood is a poor conductor of heat. It does not conduct away the heat of your hand,and the wooden rod stays comfortably warm in your hand.
