If a piece of copper is heated in the air what will happen to the mass of the piece of metal?
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.
What else can I help you with?
When a piece of copper is heated in presence of air its weight?
When a piece of copper is heated in the presence of air, it can react with oxygen to form copper oxide. This can result in an increase in weight due to the addition of oxygen atoms from the air to the copper atoms.
What happens when a piece of metal is always heated?
It will bend eventually because u have heated it up so much it wouldn't be able to function It becomes molten like the lava in the earth.
When one end of a piece of metal is heated what happens?
When one end of a piece of metal is heated, the metal molecules gain energy and vibrate more rapidly. This causes the molecules to expand, leading to the expansion of the metal itself. As a result, the metal will bend or warp due to the uneven distribution of heat throughout its structure.
Why nothing happens when a piece of copper metal is placed in zinc sulphate solution?
Copper COULD replace the zinc ion to form a copper ion and zinc metal IF it were more reactive (ignoble, base metal) than zinc. However the opposite is true!Cu + Zn2+ -xx-> Cu2+ + Znis not possible,The reversed will do:Cu2+ + Zn ---> Cu + Zn2+
How much copper can be obtained from 100g of copper sulphate?
Approximately 63.5g of copper can be obtained from 100g of copper sulfate through a chemical reaction known as displacement. This reaction involves immersing a piece of metal (such as iron) in a copper sulfate solution, causing the copper ions in the solution to be replaced by the metal ions.
When a piece of copper is heated in presence of air its weight?
When a piece of copper is heated in the presence of air, it can react with oxygen to form copper oxide. This can result in an increase in weight due to the addition of oxygen atoms from the air to the copper atoms.
Why is it when a piece of copper is folded squashed and heated in air only the outside of the copper is black?
The black coating you see is a coating of copper oxide, which forms when the hot metal reacts with air. no air can reach the inside, so it does not react to form black copper oxide.
Take a copper ring that looks like an O and cut a segment so it looks like the letter C Would the gap grow wider or more narrow as the metal expands if you were to heat the metal and explain?
You answered your own question with "as the metal expands." The gap stays proportionally the same, because the whole piece of copper expands when it is heated. It isn't relevant that someone cut out a piece of it, because the copper is completely unaware of this. It expands because you heated it, causing its atoms to move apart. This expansion occurs everywhere in the copper, but obviously not in the gap (there's nothing there but air). You may be thinking something like, "Well then the copper must close the gap," but you have to remember that ALL of the copper expands. You get a bigger version of what you had before you heated it. Tight pipe and machinery fittings are accomplished using this method. Heat it to expand, cool it to shrink.
What happens when a piece of metal is always heated?

When a piece of mild steel is heated by the application of an electric arc the metal?
contracts (get smaller)
If you tie piece of copper wire a end of a exhaust.. what will happen?
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.
When one end of a piece of metal is heated what happens?
When one end of a piece of metal is heated, the metal molecules gain energy and vibrate more rapidly. This causes the molecules to expand, leading to the expansion of the metal itself. As a result, the metal will bend or warp due to the uneven distribution of heat throughout its structure.

What will happen when a hot piece of metal is attached to cold piece of metal?
Thermal energy will move from the hot to the cold until their temperatures are identical.
What is 14kb?
14KB hallmark is a 14K gold plated metal piece. The base metal would be something such as steel or copper, but certainly not of a metal of significant value.
Pieces of metal are heated by varying amounts in a flame The hottest of the pieces will be the one that sHow is most prominently which color?
The hottest piece of metal will appear white or bluish-white in color. This is because as the temperature increases, the metal emits light in the visible spectrum, with higher temperatures corresponding to bluer colors.
Will a strong magnet attract a piece of copper?
no it wont because copper is not a type of magnet even though it is a metal
