Answer 1

Part 1: Reversible changes

The reversible changes are the changes that can be reversed easily and the original substance can be obtained back.

Part 2: Examples of reversible substances

• Melting of ice: When ice melts, it changed into liquid form but on freezing the liquid form of ice gets converted into its original solid form.
• Boiling of water: When water starts boiling it gets converted into vapors and these vapors condensed back to form water again.
• Drying of clothes: When wet clothes are put under the sun, evaporation takes place and clothes get dried. If we soak the same cloth in water, it changes into a wet cloth again.
