this is because iron has a very high melting point and therefore at room temperature it remains as a solid......
The temperature change of the iron rod can be calculated using the formula: ( q = mcΔT ), where q is the heat absorbed, m is the mass of the iron rod, c is the specific heat capacity of iron, and ΔT is the temperature change. Rearranging the formula to solve for ΔT, we have: ( ΔT = \frac{q}{mc} ). Plugging in the values: ( ΔT = \frac{50.0 J}{(15.0 g)(0.449 J/g°C)} ) = 2.22 °C.
If the rod is made from pure iron it is not a mixture.
A short standard iron bar is a solid, straight metal rod typically made of iron or steel, with a standard length that is shorter than average for a standard iron bar. It is commonly used in construction, manufacturing, and other industrial applications for structural support or reinforcement.
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.
Iron rod is a conductive material. You will get electrocuted if you touch a live wire with any conductive material like iron rod. It could be fatal to do so.
The temperature of the solid iron rod will depend on its surroundings and any heat sources or cooling mechanisms that may be affecting it. In general, the temperature of a solid iron rod will be the same as its surroundings if it has reached thermal equilibrium. However, if there are heat sources or cooling mechanisms in the vicinity, the temperature of the rod may differ.
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.
Dangerous in what sense? If you mean toxic, the answer is generally no, though iron poisoning is possible if you ingest too much. Fine iron powder can be flammable if dispersed in air. A solid iron rod can be an effective blunt weapon.

It will become shorter as it cools. Heating causes most metals to expand in volume.
Generally speaking conductivity of metals decreases as the temperature increases.
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.
The temperature change of the iron rod can be calculated using the formula: ( q = mcΔT ), where q is the heat absorbed, m is the mass of the iron rod, c is the specific heat capacity of iron, and ΔT is the temperature change. Rearranging the formula to solve for ΔT, we have: ( ΔT = \frac{q}{mc} ). Plugging in the values: ( ΔT = \frac{50.0 J}{(15.0 g)(0.449 J/g°C)} ) = 2.22 °C.

Melting an iron rod is a physical change
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.
