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:

• In a physical change, mass is conserved (so mass doesn't increase or decrease).
• Physical changes involve changes in the state or arrangement of particles (e.g., melting of ice - water molecules change from a solid - ordered arrangement to a liquid - more disordered arrangement).
• Bonding of atoms to different atoms occurs in chemical changes (not physical changes).

Answer:

The particles can arrange in different ways.
