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.
What could cause a physical change in a solid piece of sodium metal?
Exposure to air or moisture can cause sodium metal to oxidize and form sodium hydroxide, a different chemical compound. This chemical reaction would result in a physical change in the appearance and properties of the sodium metal.
How is bending a metal a physical change?
Bending a metal is a physical change because it does not alter the chemical composition of the metal. The change is reversible, meaning the metal can be straightened back to its original shape without altering its properties.
What causes properties of metal to change?
What can cause properties of metal to change is by applying heat to it. By this, it makes it a liquid and then over time as it dries, and forms a solid.
Is a piece of metal is bent in half a chemical change?
It is a physical change because only its shape changed, not its chemical composition.
Does metal expand when heated or cooled?
No. A chemical change occurs only when a new substance is produced with new and different properties. In your example, a physical change occurred because only the metal's physical properties were affected. Nothing new was created.
Which of the following could cause a physical change in a solid piece of sodium metal?
Heating the solid piece of sodium metal can cause a physical change by melting it into a liquid. Cooling the liquid sodium back to its solid state would also be a physical change.
What can cause a physical change in solid piece of sodium metal?

Is tarnishing of metal a physical or chemical change?
Tarnishing of metal is a chemical change because it involves a reaction between the metal and substances in the environment (such as oxygen or sulfur compounds) that forms a new compound on the surface of the metal, altering its properties.
Is the luster of platinum jewelry a physical change?
Yes, the luster of platinum jewelry is a physical change. The luster is a result of the surface properties of the platinum metal, such as its reflection of light, without any alteration to the chemical composition of the metal.
Is the metal classified as chemical or physical?
it is physical because when the metal melts it is still metal. it doesn't change to a new subtance.--------------------------------------A metal is a chemical element, not a property; but in some situations chemist use the expression metallic characteristics (or properties).
