Why a copper wire in a closed circuit does not get heated?
j
Is it safe to breathe in the fumes from heated copper wire?
Hot copper wire gives off no fumes.However if you are talking about insulated copper wire, the insulation will give off fumes. Depending on the type of insulation it can be anywhere from totally safe to deadly!
What are the elements of copper wire?
Electrical wire can consist of several different elements from Aluminum to copper and even steel. Many types of wire have been made from silver and also gold, depending on the application, and it's no uncommon to plate the wire with another metal to avoid corrosion or rust.
Dose recycled copper wire be come new copper wire?
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
What happen if copper wire dip in solution of magnesium chloride?
When copper wire is dipped in a solution of magnesium chloride, no significant reaction occurs because copper is less reactive than magnesium. The magnesium ions in the solution do not displace copper from its metallic state. As a result, the copper wire remains unchanged in appearance and composition. However, if the solution were to contain a more reactive metal, such as zinc, a displacement reaction could occur.
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.
What is the compound formed after plunging a heated copper wire into a methanol?
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.
When current passes why copper wire does not get heated while the bulb gets heated?
copper wire is good conductor of heat but bulb is bad conductor of heat.
What happens to the matter in copper wire when heated?
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.
What will happen when copper is heated?
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.

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.
What happens to the resistance of a copper wire when it is heated?
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.
What happens when a piece copper wire is heated in the outer region of the flame until its red hot?
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.
What is the evidence that indicates that both physical and chemical changes occur when a copper wire is heated in a Bunsen burner flame?
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.
What is the Balanced equation for the reaction of heated copper wire and methanol?
CuO + CH3OH --> HCHO + Cu + H2O
Is it safe to breathe in the fumes from heated copper wire?
