Answer 2

Answer:

• When we heat an iron rod, some of the healing energy collected by the iron rod is released as light.

• When the temperature of the rod exceeds the melting point (1538 degrees), it will begin to melt if you continue to heat it.

• The heat conductivity of iron is excellent. The heat will be distributed evenly across the entire bar due to conduction. We'll also notice the bar's thermal expansion.
