Melting ice: When solid ice is exposed to heat, it melts and turns into liquid water. This process is reversible, as when the liquid water is cooled, it solidifies back into ice.

Opening and closing a door: You can open and close a door multiple times, which demonstrates a reversible action. Opening the door allows access, while closing it restricts entry.

Charging and discharging a battery: A battery can be charged by providing electrical energy to it, storing the energy for later use. Conversely, it can be discharged by using the stored energy to power a device. This process can be repeated, making it reversible.

Evaporation and condensation: When water is heated, it evaporates and turns into vapor. This vapor can then be cooled, causing it to condense back into liquid water. The process of evaporation and condensation is reversible.

Inflation and deflation of a balloon: By blowing air into a balloon, it inflates and expands. Releasing the air from the balloon causes it to deflate and return to its original size. This action is reversible as the balloon can be inflated and deflated repeatedly.
