What happens when you boil water in a kettle?

The water inside the kettle boils, evaporates in the form of bubbles and comes out of the spout as steam. Then when the steam makes contact with the cold air outside the kettle, it quickly condenses back to tiny droplets of water which you see as water vapor.

What really happens when you boil water?

When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

What type of change is boiling water?
