Is solidification of cooking oil an example chemical change?

Solidification of cooking oil is not an example of a chemical change. A chemical change occurs when the chemical composition of a substance is altered, resulting in the formation of one or more new substances with different properties. In the case of cooking oil, solidification is a physical change.

When cooking oil solidifies, it undergoes a phase transition from a liquid to a solid state without any change in its chemical composition. The oil molecules rearrange themselves into a more ordered, crystalline structure, but the chemical bonds between the atoms remain the same. As a result, the solidified oil can be melted back into a liquid state without changing its chemical identity.
