1. A physical change cannot be reversed.

Answer 1

Correct statement: A physical change can be reversed.

• Physical changes are those that occur only in terms of the physical characteristics of the substance in concern.
• The freezing of water can explain physical changes.
• The condition of water transforms from liquid to solid when the temperature of the water is reduced below its freezing point.
• However, if the temperature of this solid water or ice is raised again, the same amount of water is obtained as before.
• As a result, we may state that physical alterations can be reversed.
