Can you reverse water boiling on the stove?

You can't reverse water boiling on the stove in the sense of making the water go back to its previous state just by turning off the heat. Here's why:

* Boiling is a physical change: Boiling water is a change of state from liquid to gas. This change is driven by heat energy.

* Energy transfer is unidirectional: While you can input energy (heat) to make water boil, you can't easily extract that energy back into the stove.

* Entropy: The universe tends towards disorder. Once the water molecules have become steam, they're more dispersed and disordered. Getting them back into a neat, liquid form requires external work.

What you CAN do:

* Cool the water down: By removing the heat source (turning off the stove) and allowing the water to cool, you can condense the steam back into liquid water.

* Use a refrigerator or freezer: You can rapidly cool the water down and condense the steam into liquid water much faster using a refrigerator or freezer.

In short: You can't "reverse" the boiling process by simply turning off the stove. You need to remove the heat energy added to the water to condense the steam back into liquid.
