No, thermal expansion is a physical property, not a chemical property. It refers to the tendency of matter to change in shape, area, and volume in response to a change in temperature. It does not involve any change in the chemical composition of the substance.
Yes, thermal expansion and contraction are physical changes. They result from the change in temperature of a material, causing its molecules to either spread out (expansion) or come closer together (contraction), without altering the chemical composition of the substance.
Physical. The mercury doesn't change.
it is a chemical change
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
No. "Chemical change" means that the bonds between atoms are rearranged.
No, thermal expansion is a physical change, not a chemical change. It occurs when a material expands or contracts in response to changes in temperature, without any change in the chemical composition of the material.
is air expantion a chemical or physical change?
physical change.the condition can be reversed by changing the temperature & it is only a temporary change.

No. It's a physical change since it's still the same liquid.
Expansion is a physical property.
