When air is passed through a heated tube containing finely divided copper the component that is absorbed in the process is?
When air is passed through a heated tube containing finely divided copper, oxygen from the air is absorbed by the copper. This reaction leads to the formation of copper oxide, as the copper reacts with the oxygen at elevated temperatures. The process effectively reduces the concentration of oxygen in the air passing through the tube.
What is formed when copper oxide is heated in a test tube with carbon?
When copper oxide is heated in a test tube with carbon, carbon acts as a reducing agent and reacts with copper oxide to form copper metal and carbon dioxide. This is a type of redox reaction where copper gains electrons from carbon, resulting in the reduction of copper oxide to copper.
Why is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
What material used in boiler tube in indian power plant?
Usually Alloy steel is used, copper and brass are also used as boiler tube materials
Can you light a light bulb by holding a copper tube and a steel tube wired to a light bulb?
Yes, you can create a simple battery by holding a copper tube and a steel tube in an acidic solution like lemon juice, which will generate a small electric current. By wiring this to a light bulb, you can light it up. This experiment demonstrates the principles of making a battery using dissimilar metals.
What are the classification of a copper tube?
Copper tube is a favorite choice for plumbing, heating, cooling and other systems. Copper tube is most often used for supply of hot and cold tap water as refrigerant line in HVAC systems. There are two basic types of copper tube, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance, but is becoming very costly. alliedallcityinc.com
What observation can be seen in a combustion tube when hydrogen gas is passed over heated copper II oxide?
When hydrogen gas is passed over heated copper II oxide in a combustion tube, the copper II oxide will be reduced, resulting in the formation of copper metal and water. The color change from black (copper II oxide) to brown (copper metal) can be observed in the tube, along with the release of steam.
What copper tube is available when using the grooved method of joining?
Grooved method? Threads on the end of the pipe? There is no tube or pipe in copper with threads. You can end a copper pipe with a connection that is threaded to accept steel pipe.
When a magnet is dropped inside a copper tube its exit is delayed by a few minutes why?
This effect has nothing to do with the magnet sticking to the side of the copper. Magnets will only stick to ferromagnetic substances such as iron and steel, not copper. The actual physics of this experiment is more subtle. The magnet falling down the tube results in a changing magnetic field within the copper tube. This changing magnetic field produces a current within the tube. That current creates a new magnetic field within the tube which slows down the magnet.
What happens to color of copper suphate crystals when heated in a test tube?
The dehydrated copper sulfate is grayish-white.
Do you have to replace the copper pipes when replacing ac unit?
no need to change the copper tube if the capacity of the unit is same.
Why does a magnet slow down when moving through a copper tube?
A magnet slows down when moving through a copper tube because the magnetic field generated by the moving magnet induces electric currents in the copper tube, creating an opposing magnetic field that resists the motion of the magnet. This resistance, known as electromagnetic induction, causes the magnet to slow down as it moves through the tube.
What is the function of capillary tube?
The capillary tube is used on the inside of the refrigerators. It is a long copper tubing that is used as a thruster.
What is formed when copper oxide is heated in a test tube with carbon?
When copper oxide is heated in a test tube with carbon, carbon acts as a reducing agent and reacts with copper oxide to form copper metal and carbon dioxide. This is a type of redox reaction where copper gains electrons from carbon, resulting in the reduction of copper oxide to copper.
What is the blood red residue formed in a glass test tube when copper carbonate is heated vigourously with carbon?
Elemental copper.
How does dropping a magnet through a copper tube demonstrate the concept of electromagnetic induction?
Dropping a magnet through a copper tube demonstrates electromagnetic induction by showing how the changing magnetic field created by the moving magnet induces an electric current in the copper tube. This phenomenon is a key principle of electromagnetism and is commonly used in devices like generators and transformers.
How does the use of a magnet through a copper tube demonstrate the principles of electromagnetic induction?
When a magnet is moved through a copper tube, it creates a changing magnetic field. This changing magnetic field induces an electric current in the copper tube through electromagnetic induction. This demonstrates the principles of electromagnetic induction, where a changing magnetic field can generate an electric current in a conductor.
