Copper itself does not float in water due to its density being greater than that of water. However, if you are referring to a chemical reaction that might cause copper to appear to float, certain chemicals can create a buoyant effect by generating gas bubbles. For example, adding an acid like hydrochloric acid to copper can produce hydrogen gas, which could create enough bubbles to momentarily lift small pieces of copper. However, this is a temporary effect and not a true flotation of the copper itself.
What else can I help you with?
Does copper have density?
Copper has a density of about 8.96 g/cm3 and don't float on water.
What makes an item to float or sink in water?
This depends on the density of this item: more denser than water-sink, less denser than water-float.
When copper sulfate salt and water are mixed is it a chemical or physical change?
When copper sulfate salt is mixed with water, it undergoes a physical change. The salt dissolves in the water, resulting in a homogeneous solution, but the chemical composition of the copper sulfate remains unchanged. This process is reversible, as the water can be evaporated to retrieve the original salt.
What chemical in copper makes it rust?
The only chemical that could make something rust is iron; "rust" refers specifically to the corrosion of iron, so copper cannot rust. However, its corrosion is caused by copper itself being oxidised and forming compounds which are water soluble and also easier to damage.
Is copper sulphate dissolves in water a physical or chemical change?
A physical change is different from a chemical change in two ways:1) In a physical change no new substances are made; in a chemical change new substances are made.2) A physical change can be easily reversed; a chemical change cannot be easily reversed.Dissolving copper sulphate in water does not produce a new substance. The copper sulphate solution is a mixture, not a pure substance.Also, by evaporating the water you can easily get the copper sulphate back again.So, dissolving copper sulphate is a physical change.Sometimes, though, when water is added to copper sulphate, it reacts with the water to form copper sulphate pentahydrate, which is a new compound. This would be a chemical change, but actually dissolving it is indeed a physical change only.See these sites for more information:http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/chem_react_2.shtmlhttp://www.chem4kids.com/files/matter_chemphys.html
What chemical makes copper float?
If it is a thin, small piece of copper put it in water with soap and I think it will float Copper will float in Mercury. Copper will float in Uranium Hexafluoride but good luck getting your hands on any of that.
Does a copper wire float or sink in water?
A copper wire will sink in water because copper is denser than water.
Is reactivity to water a physical property of copper?
Yes, reactivity to water is a chemical property of copper, not a physical property. Copper does not react with water at room temperature, but it can slowly react with water when exposed to high temperatures or steam to form copper oxide.
How do you know if a chemical will float in water?
A chemical will float in water if its density is less than the density of water (approximately 1 g/cm3). This can be determined by comparing the densities of the chemical and water. If the chemical's density is less than water, it will float; if it is greater, it will sink.
What makes boats float on water?
Bouyancy is what makes a boat float
Can a copper coin float in water?
No, a copper coin will not float in water because it is denser than water. This means that the weight of the coin is greater than the buoyant force it experiences in water, causing it to sink.
What specific gravity allows a chemical to float in water?
A specific gravity less than 1 allows a chemical to float in water. This means the chemical is less dense than water and so it will float on the water's surface instead of sinking.
Does copper have density?
Copper has a density of about 8.96 g/cm3 and don't float on water.
Will copper float in fresh water?
Copper is more dense than water so a piece of copper will sink and not float in fresh water. However if the copper is formed into a container like shape similar to that of a boat it will stay on top of the water. For a better understanding of why, look up Archimedes Principle.
Is adding water to heated copper sulfate crystals chemical or physical?
Adding water to heated copper sulfate crystals is a chemical change. When water is added to heated copper sulfate crystals, the copper sulfate undergoes a chemical reaction where it dissolves in the water to form a solution. This is a chemical change because the chemical composition of the copper sulfate is altered during the process.
Does copper wire sink or float?
A short piece may be supported by the surface tension of water, but a coil of copper wire would sink.
Does copper sink in water?
Copper does not sink in water.. An object with higher density than water sinks while an object with lower density than water floats..
