Is polishing a metal a metal a physical change?
Yes it is. It is not altering the chemical makeup of the substance.
Is using hot water to expand a metal cup a physical or chemical change?
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.
Why is melting metal a physical change?
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.
Is pounding and shaping horeshoe a chemical or physical change?
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.
Is bending a metal wire a physical or chemical change?
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
Is hammering copper metal a physical or chemical change?
It is a physical change because you are changing the shape of the metal.
Is polishing a metal a metal a physical change?
Yes it is. It is not altering the chemical makeup of the substance.
Is a piece of metal a physical change?
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.
Why is Metal Knife is sharpened a physical change?
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.
Why rusting is a chemical change and not a physical change?
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.
Is using hot water to expand a metal cup a physical or chemical change?
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.
Why is melting metal a physical change?
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.
Is bending a metal wire a physical or chemical change?
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
Is non rusting metal a physical change?
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.
Is hammering metal into a flat sheet physical or chemical change?
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
What is a change to a material that does not change its composition?
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.
Is denting a piece of metal a physical or chemical change?
Physical. The properties of the metal do not change, and it can be undented.
