Understand the Problem

The question is asking us to identify the process among the provided options that causes a physical change in the shape of a material. The focus is on understanding what constitutes a physical change as opposed to a chemical change.

More Information

Grinding is a process that mechanically alters the shape and size of material, resulting in a physical change without altering its chemical structure. This makes it a physical process as opposed to chemical processes like burning.

Tips

Common mistakes involve confusing chemical changes (like burning) with physical changes. Remember that physical changes do not alter the material's chemical structure.
