Is bacon grease solidifying physical or chemical change?

Solidifying bacon grease is a physical change.

Explanation:

A physical change is a change in the state or form of matter without a change in the chemical composition of the substance. In the case of bacon grease, when it solidifies, it simply changes from a liquid state to a solid state without any alteration in its chemical structure or composition. The molecules of bacon grease remain the same before and after solidification.
