Answer

Brief Explanations:

A physical change is one where the substance retains its original properties and no new substance is formed. A chemical change results in the formation of a new substance. A state change or particle - size change alone does not necessarily mean a chemical change has occurred if the substance's identity remains the same. Calcium carbonate undergoing a state or particle - size change while retaining its original properties is a physical change.

Answer:

physical change because even though a particle size change was observed, the calcium carbonate retained its original properties and was not transformed into a new substance
