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.

∙ 10y agoIf heated in a vacuum the mass of a piece of copper would not change until it started to boil off. In an atmosphere of oxygen or other reactive gas, chemical changes might cause a change of mass as gas is absorbed.
Wiki User
∙ 13y agoYou will not detect any change in the mass of copper as a result of heating it, although in theory, there is a very slight increase in mass which results from adding heat energy, in accordance with Einstein's famous equation, e = mc2.
Wiki User
∙ 13y agothe mass will be increased because the oxygen will be added in a chemical reaction to form copper II oxide.
Cu (s) + O2 (g) >>>> CuO (s)

∙ 16y agoits the same. you cant create or destroy mass
Wiki User
∙ 14y agoIf you are heating copper pieces, they will turn from brown then to a greenish sort of colour then black.
Wiki User
∙ 13y agoThe mass decreases because
copper carbonate (heat)--> copper oxide + carbon dioxide
hope this helps all you people who are stuck :)
Wiki User
∙ 14y agoThe mass stays the same.
Melting is a physical process and not a chemical reaction, and so there will be exactly the same amount of copper after menting as before.

∙ 8y agoCopper is transformed in copper(II) oxide - CuO.

When a piece of copper is placed in a lead nitrate solution what will happen?
No Reaction Occurs (:
When one end of a piece of metal is heated what happens?
the partcles get closer together or the particles get bigger. you decide
What happen when you put a piece of copper in silver nitrate solution?
it goes all white and puffy because the copper replaces the silver in the solution
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.
What happens when a piece copper wire is heated in the outer region of the flame until its red hot?
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.
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.
When a piece of mild steel is heated by the application of an electric arc the metal?
contracts (get smaller)
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
When a piece of copper is placed in a lead nitrate solution what will happen?
No Reaction Occurs (:
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 burning copper and rubber what makes the different colors in the flame?
Any piece of copper heated will do the same thing. When heated, the colored coating on the copper is called "scale," and consists of a thin layer of copper oxide on the surface of the copper. Depending on the thickness of the layer and its temperature, the scale can be some very interesting colors, such as red, blue, brown, and pink.

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.
