After 100 0C (at normal pressure) water become a gas (water vapours).
Under 0 0C water become a solid (ice).
volume of liquids
When water is boiled it changes from liquid to a gas.
Water changes from a liquid phase to a gaseous phase when it is boiled.
When water boils it changes from a liquid state to a gaseous state.
It changes to a gas (steam).
The state of matter changes from liquid to gas when water is boiled in a pan on a stove.
It's still water, it just changes from a liquid to a gas.
When water is boiled, impurities and air bubbles are removed, resulting in a clearer liquid. This clear water freezes more uniformly, allowing light to pass through without being scattered, giving it a clear appearance when frozen.
Boiled water will not rust as rusting is a chemical reaction between iron and oxygen in the presence of water. Boiling water simply changes its state from liquid to gas (water vapor) and does not directly cause rusting.
The amount stays the same but some of it changes to steam and water vapour and it will disappear.
Water as a vapour (gas?) has to condense back to water, which can then become a solid if frozen.
The Tardigrades can live for a decade without water, being frozen or boiled, float in space, exposed to radiation, and live for 200 years.
