Answer:
The correct option is: The particles can arrange in different ways.
In a physical change, the substance undergoes a transformation that does not involve a change in its chemical composition. It means the original substance remains the same, but its physical properties, such as shape, state, or arrangement of particles, may change.
Options (i) The mass can increase and (iii) The mass can decrease are not generally observed in physical changes because the total mass of the substance remains the same. The law of conservation of mass states that mass cannot be created or destroyed in ordinary chemical reactions or physical changes.
Option (iv) The atoms can bond to different atoms refers to a chemical change where the atoms rearrange to form new substances with different chemical compositions. This is not typically a characteristic of physical changes.
Therefore, the correct answer is: The particles can arrange in different ways.
