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.

Is hammering copper metal a physical or chemical change?
Hammering copper metal is a physical change because it alters the shape and appearance of the metal without changing its chemical composition.
Is hammering metal into a flat sheet physical change?
Yes, hammering metal into a flat sheet is a physical change. The metallic bonds between atoms remain intact as the metal is reshaped, just the arrangement of atoms changes.
Is a metal surface being ground a chemical change?
Grinding a metal surface is a physical change, not a chemical change. The metal is being physically altered in shape and size, but its chemical composition remains the same.
Is denting a piece of metal a physical or chemical change?
Denting a piece of metal is a physical change, not a chemical change. This is because the composition and properties of the metal remain the same even though its shape has been altered.
Is a silver metallic color of sodium metal a physical or chemical change?
The formation of a silver metallic color on sodium metal is a physical change. This change is due to the reflection of light by the metal's surface, and the silver color is a property change and does not involve a change in the chemical composition of the sodium metal.
Is hammering copper metal a physical or chemical change?
Hammering copper metal is a physical change because it alters the shape and appearance of the metal without changing its chemical composition.
Is hammering metal into a flat sheet physical change?
Yes, hammering metal into a flat sheet is a physical change. The metallic bonds between atoms remain intact as the metal is reshaped, just the arrangement of atoms changes.
What are examples of chemical reaction?
Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.
shaping horseshoes is it a physical or chemical?
Shaping horseshoes is a physical change because the process involves bending, hammering, and stretching the metal without altering its chemical composition. The change is reversible, as the horseshoe can be reshaped back to its original form if needed.
Is pounded metal a physical or chemical change?
Physical change
Is metal corroding a physical change or chemical change?
Corrosion is a chemical change
What is Heating up metal with a flame is that a physical or chemical change?
No, it is a chemical change. The metal oxide formed is a new substance.
Is corrosion of a piece of metal chemical or physical change?
chemical change
Is vaporizing metal a chemical or physical change?
Vaporization is a physical change.
Is a metal surface being ground a chemical change?
Grinding a metal surface is a physical change, not a chemical change. The metal is being physically altered in shape and size, but its chemical composition remains the same.
Is bending a metal rod chemical or physical change?
Physical Change, the metal has the same chemical structure and only the shape of the bar has changed
Is denting a piece of metal a physical or chemical change?
Denting a piece of metal is a physical change, not a chemical change. This is because the composition and properties of the metal remain the same even though its shape has been altered.
