Is boiling water irreversible

Answer 1

From a thermodynamics standpoint, it depends how the process is carried out. If the system (the water) and the surroundings remain close to equilibrium during the entire process then the water boils reversibly. So if the change in temperature is approximately zero throughout the process and the process takes an infinitely long amount of time to carry out you can reversibly boil water.

If you were asking whether water vapor can turn back into liquid water, then yes the process of turning water into water vapor is reversible.

Answer 2

It's a reversible change. You can cool the boiled water (steam) back down and it turns back into liquid water. A chemical reaction causes one or more chemicals to become other chemicals. As long as the water is still water, regardless of temperature, no chemical reaction has taken place.

Answer 3

Nope. If you turn the heat off so the temperature drops below 100C, you will have non-boiling water. When the steam's temperature drops below the vaporization temperature it will return to liquid state.

Answer 4

Boiling water is generally considered a reversible change because the water vapor can be condensed back into liquid water through cooling.

Answer 5

Reversible cuz you can turn the heat of and it wont boil as if it were permenant it would stay boling FOREVER

Answer 6

Irreversible... Boiling removes the starch from the flesh of the potatoes. Even if you soaked the cooked potatoes in a starch solution - they would never revert back to their raw state.

Answer 7

Boiling water is a phase change which is a physical change and reversible.

Answer 8

Boiling is not irreversible; liquefaction is the reverse process.

Answer 9

Boiling water into steam is a REVERSIBLE process. The steam can be collected and converted back into liquid water. This process is a physical change, not a chemical change.
