Yes. The wire and the block are still composed of the same material - only the shape has changed.
Yes it is. It is not altering the chemical makeup of the substance.
Using hot water to expand a metal cup is a physical change. The change in size and shape of the cup is due to the expansion of the metal atoms when heated, but the chemical composition of the metal cup remains the same.
Melting metal is a physical change because it does not change the composition of the metal. The metal goes from a solid state to a liquid state, but it is still the same substance with the same chemical makeup.
Pounding and shaping a horseshoe is a physical change. This process involves altering the shape and size of the metal without changing its chemical composition. The properties of the metal, such as its structure and appearance, may change, but the material itself remains the same. Thus, it is classified as a physical change.
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
It is a physical change because you are changing the shape of the metal.
Yes it is. It is not altering the chemical makeup of the substance.
I think dhatt the answer is a physical change because if you just bent it then surley you can unbent it and still have a piece of metal.
Sharpening a metal knife is considered a physical change because the composition of the metal remains the same before and after sharpening. The process only alters the shape and size of the knife's edge without changing its chemical composition.
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.
Using hot water to expand a metal cup is a physical change. The change in size and shape of the cup is due to the expansion of the metal atoms when heated, but the chemical composition of the metal cup remains the same.
Melting metal is a physical change because it does not change the composition of the metal. The metal goes from a solid state to a liquid state, but it is still the same substance with the same chemical makeup.
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
The kind of change described is referred to as a physical change. Examples of physical changes include, but are not limited to, changing the temperature or state of a substance, changing the shape of a substance, and breaking a substance into smaller pieces. A change that alters a material's composition would be classified as a chemical change.
Physical. The properties of the metal do not change, and it can be undented.
