The resistance will go up.
The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
this is because copper wire offers no resistance and thus electric current passes through them without producing heat energy whereas in nichrome offers a large resistance and thus the mechanical energy of the drifting electrons changes to heat energy rapidly .
Copper.
It remains as metallic copper.
copper gains heat
Copper sulfate is formed.
Copper vessels are easily corroded.
the copper oxide will turn red

Copper(II) hydroxide and sodium nitrate are thermally decomposed to oxides by heating.
when copper and zinc are heated, they create brass :)
No, aluminum has a higher resistance than copper.
