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.
The reaction of copper with heat is a physical change because no new substances are formed. When copper is heated, it undergoes a change in state from solid to liquid without changing its chemical composition.
The melting of copper is a physical change because it involves a change in the state of matter from solid to liquid without altering the chemical composition of copper itself.
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 metal conducting electricity is a physical property, not a physical or chemical change. Conductivity relates to how electrons move within a material, which does not alter the chemical composition of the copper itself.
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.
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.
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.
The melting of copper is a physical change because it involves a change in the state of matter from solid to liquid without altering the chemical composition of copper itself.
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
The reaction of copper with heat is a physical change because no new substances are formed. When copper is heated, it undergoes a change in state from solid to liquid without changing its chemical composition.
