Is expansion physical or chemical change?
Expansion is a physical change because it involves a change in the state or size of matter without altering its chemical composition.
Is expansion of air chemical change?
No. "Chemical change" means that the bonds between atoms are rearranged.
Is thermal expansion a chemical change?
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.
What is air expansion apparatus?
is air expantion a chemical or physical change?
Is thermal expansion a chemical property?
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.
Is thermal expansion and contraction a physical change?
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.
Is liquid expanding in a thermometer a chemical change?
No. It's a physical change since it's still the same liquid.
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
Is stapling an envelope a physical change or chemical?
