Physical and chemical changes

physical change because only ionic bonds between $\mathrm{O}{\phantom{A}}^{2-}$‍ ions are broken

physical change because only dipole-dipole forces between $\mathrm{O}{\phantom{A}}_3$‍ molecules are disrupted

chemical change because $\mathrm{O}-\mathrm{O}$‍ bonds are broken and new $\mathrm{O}-\mathrm{O}$‍ bonds are formed

chemical change because covalent bonds between $\mathrm{O}{\phantom{A}}_3$‍ molecules are broken
