Is water vapour from the air condensing on a cold drink can irreversible?

Yes, the condensation of water vapor from the air on a cold drink can is typically considered an irreversible process. When water vapor cools upon contact with the cold surface of the can, it transforms into liquid water, which can then drip off or be absorbed. While the vapor can return to the air if the conditions change, the specific condensation event itself cannot be reversed without altering the temperature and pressure of the system.
