Question

which can occur in a physical change?
the mass can increase.
the particles can arrange in different ways.
the mass can decrease.
the atoms can bond to different atoms.

Explanation:

A physical change only alters the physical state or arrangement of matter, not its chemical composition or total mass. Mass is conserved in physical changes, so mass increase/decrease does not occur. Atoms bonding to different atoms is a chemical change, as it forms new substances. Rearranging particles (e.g., solid to liquid) is a physical change.

Answer:

The particles can arrange in different ways.
