That process is called transformation or transmutation where the original material undergoes a change in its chemical or physical composition resulting in a new material.
No, a physical change does not form a new material. It simply alters the state or appearance of the existing material without changing its chemical composition.
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.
