it can be any length you want.
in science experiments they are mostly quite short, but they come on rolls of like up to 5 yards.
Yes as long as you use an approved splice, such as a wire-nut.
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).
Copper will.
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
no rubber stops the flow of electricity
If a person ties a piece of copper wire at the end of the exhaust pipe on a vehicle the copper is going to heat up. When the copper heats up it will turn a rainbow of colors.
No
Yes as long as you use an approved splice, such as a wire-nut.
a copper wire carrying current
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.
The answer depends on the cross sectional area of the wire. This is not given.
He put a piece of wet cardboard on a piece of copper and then put a piece of zinc on top of that, repeated it twelve times and put a copper wire on one end and a zinc wire on the other then made the two wires touch and got an electric spark. ETN
It can differ from however long the piece of rope, wire etc. attached is.
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).

how much copper is in copper wire
No. Other things being equal, a long wire has more resistance than a short wire.
