How many electrons in copper wire?
Copper wire typically contains one free electron per atom, as copper has one electron in its outer energy level. So, the number of electrons in copper wire depends on the number of copper atoms present in the wire.
Is copper wire a mechanical mixture?
It should be a "pure" substance, but its really an alloy.
Is copper wire a pure substance mechanical mixture or a solution?
Copper wire is a pure substance, as it is made entirely of copper atoms.
What is the result after heating copper wire and sulfur powder?
Heating copper wire and sulfur powder together will result in the formation of copper sulfide. Copper sulfide is a compound where copper and sulfur atoms are chemically bonded together.
Copper wire is matter that is comprised of only one?
Copper wire is matter that is comprised of only one type of substance, which is copper. This substance is made up of copper atoms arranged in a specific pattern that gives the wire its unique properties.
How many atoms of copper are in 30.5 mg of thin copper wire?
To calculate the number of atoms in 30.5 mg of copper wire, we first need to determine the number of moles of copper using its molar mass (63.55 g/mol). Then, we use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of copper to atoms.

What happens to the resistance of copper wire as the temperature of the wire increases?
The resistance of copper wire increases as the temperature of the wire increases. This is due to the increase in collisions between free electrons and atoms in the wire, which hinders the flow of electricity.
What happens to copper wire when heated?
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.
Copper wire is bent is physical or chemical?
Bending a copper wire is a physical change because the copper itself does not undergo a chemical reaction. The arrangement of copper atoms simply changes temporarily when the wire is bent, but the properties of copper remain the same.
Is a copper wire a mechanical mixture a solution or a pure substance?
It should be a "pure" substance, but its really an alloy.
How do you calculate diameter of a copper wire conductor and how do we calculate resistance of a copper wire conductor of a particaular length?
You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage
Electric current in a copper wire is normally composed of what?
Electric current in a copper wire is composed of moving electrons. When a voltage is applied across the wire, the free electrons in the copper atoms move in response to the electric field, creating the flow of current.
