Does copper sulphate undergo any physical or chemical changes during heating?
When heated, copper sulfate undergoes a reversible physical change where it loses its water molecules (dehydration) and changes color from blue to white. This process is purely physical and does not involve any chemical reactions.
A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Is stretching wire into copper a physical or chemical change?
Stretching wire into copper is a physical change because the composition of the material remains the same. The rearrangement of copper atoms in the wire does not alter the chemical identity of the substance.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
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
Why should copper sulfate dissolution be regarded as a chemical change?
Dissolution of Copper sulphate in water is a Physical Change... It cannot be regarded as a Chemical Change.
Is copper sulphate a physical change?
Copper sulfate dissolving in water is a physical change because the chemical composition of copper sulfate remains the same. Physical changes do not alter the chemical structure of a substance.
Is copper suphlate a mixture?
Copper Sulphate (check your spelling) is a chemical compound. It can only be separated by chemical change, not by physical change. Therefore, it is not a mixture.
Does copper sulphate undergo any physical or chemical changes during heating?
When heated, copper sulfate undergoes a reversible physical change where it loses its water molecules (dehydration) and changes color from blue to white. This process is purely physical and does not involve any chemical reactions.
Is crystallization of copper sulphate a physical change?
Yes, crystallization of copper sulfate is considered a physical change. This process involves the copper sulfate molecules arranging themselves into a specific crystal lattice structure without changing their chemical composition. Therefore, it does not involve any chemical reactions.
Is copper a physical or chemical change?
its a physical change
A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is hammered copper a physical change?
Yes, hammered copper is a physical change. When copper is hammered, its shape and size change, but its chemical composition remains the same.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Is copper in a Bunsen burner a physical or chemical change?
Using a Bunsen burner to heat copper is a physical change. The copper undergoes a change in its physical state from solid to liquid without changing its chemical composition.
