Sand and glass have different chemical formulas, so that means that the atoms are rearranged and this is a chemical reaction.
there is evidence that sand to glass is chemical change but it is also a physical change .
Changing sand to glass represents a chemical change due to the creation of a new substance with different properties. It involves the rearrangement of atoms and is characterized by permanency, as it is not easily reversible. Evidence for this includes changes in chemical composition, formation of new substances, and alterations in physical properties.
