Question

what happens when one end of a copper wire is heated??​

Answer 1

Answer:

Conducting heat

The ions are vibrating and the electrons can move through the copper (rather like a gas). Figure 3 shows what happens when one end of the piece of copper gets hotter. The copper ions at the hot end vibrate more. Note: the electrons have been left out of the picture to keep it clear.

Answer 2

Explanation:

Heated copper metal reacts with oxygen to form the black copper oxide. The copper oxide can then react with the hydrogen gas to form the copper metal and water. When the funnel is removed from the hydrogen stream, the copper was still be warm enough to be oxidized by the air again.
