It has to be cooled below 100 degrees Celsius (212 degrees Fahrenheit)
The reverse process is condensation, formation of a liquid.
They make the water into steam. Part of it is transferred into latent heat, which is heat water requires to become steam. As you keep heating the water (assuming it's a closed flask), then eventually all the water will become steam.
When water is in the vapour form of steam, it is in a gaseous state.
Water boiling to become steam is an example of a liquid to gas phase change.
Steam has the most energy as its particles are in the gaseous state and move faster than particles in liquid water or ice, which are in the solid or liquid state respectively. Freezing water has a similar amount of energy as liquid water since they are at the same temperature.

Liquid water becomes water vapor, which is the gaseous state of water, when it absorbs enough heat and evaporates.
Water has 3 phases. These phases include steam, liquid and ice. Ice is the most dense, followed by liquid and then steam.
Water boiling to become steam is an example of a liquid to gas phase change.
Liquid water changes into steam when it is heated to its boiling point, causing the water molecules to have enough energy to overcome the attractive forces holding them together in the liquid state. As the molecules gain energy, they break free from the liquid's surface and become a gas, forming steam.
An example of a change of state is an ice cube melting and becoming liquid water, or liquid water boiling to become steam.
The reverse process is condensation, formation of a liquid.
The three forms (solid, liquid and vapour) are interchangeable and can change from one physical state to another. Chemically, they exist as H2O molecules throughout.Solid ice melts on heating to become liquid water. Liquid water boils on heating to become gaseous steam.Conversely, gaseous steam condenses on cooling to become liquid water. Liquid water solidifies on cooling to become solid ice.On heating: ice -> water -> steamOn cooling: steam -> water -> ice
Air is primarily composed of gases like nitrogen, oxygen, and carbon dioxide, so it is not a liquid. Water can exist in three states: solid (ice), liquid (water), and gas (steam). Steam is the gaseous form of water, not a liquid.
Steam and vapor are in the form of a gas. Liquid water is in the form of a liquid.
When steam is a liquid or goes into a liquid state via condensation, then it is no longer deemed as gas or steam. Thus it is called liquid.
