When copper wire is heated, it expands due to thermal expansion. As it gets hotter, the electrons in the copper atoms move more freely, increasing electrical resistance. Excessive heating can cause the copper wire to melt and ultimately vaporize.
When copper wire is heated, the atoms within the wire vibrate more vigorously, leading to an increase in kinetic energy. This causes the wire to expand slightly in length and thickness. If heated excessively, the wire can eventually melt and transform into a liquid state.
When a copper wire is heated in the outer region of a flame until it's red hot, it undergoes oxidation which forms a layer of copper oxide on its surface. This layer appears as a black residue and can be easily removed through polishing to reveal the original copper surface beneath.
When a copper wire is heated with a Bunsen burner, it undergoes oxidation as it reacts with oxygen in the air, forming copper(II) oxide (CuO) on its surface. The balanced chemical equation for this reaction is: 2Cu + O2 -> 2CuO.
When a copper wire is heated in a Bunsen burner flame, the copper's color changes to become a glowing red. It won't be restored to its original appearance after cooling. Instead, it becomes a black material called copper (II) oxide, which is 79.9% copper and 20.1% oxygen (was 100% copper before it was burned). This chemical change occurred as the oxygen in the air combined with the copper during the heating process.
When copper is heated, it will expand due to increased molecular motion. If the temperature is high enough, copper will eventually melt and turn into a liquid state. Copper can also undergo a chemical reaction with oxygen in the air, leading to the formation of copper oxide on its surface.

The resistance of a copper wire increases when it is heated. This is because heating the wire causes the metal ions to vibrate more, increasing collisions with the electrons and hindering the flow of current, therefore increasing resistance.
it went up because the mass increases
Copper sulfate is formed.
It depends on what you added to the methanol before you put the heated copper wire into the methanol. The heated copper wire acted as a catalyst to speed up the reaction between the methanol and the other substance. Copper itself does not react with methanol.
copper wire is good conductor of heat but bulb is bad conductor of heat.
