Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
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.
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.
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.
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.
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.
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
Dissolution of Copper sulphate in water is a Physical Change... It cannot be regarded as a Chemical 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.
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.
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.
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.
its a physical 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.
Yes, hammered copper is a physical change. When copper is hammered, its shape and size change, but its chemical composition remains the same.
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.
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical 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.
