Here's why:
* Heat energy: When you heat water, you're adding energy to the water molecules.
* Increased movement: This added energy causes the water molecules to move faster and farther apart.
* Breaking bonds: Eventually, the molecules have enough energy to break the bonds that hold them together in the liquid state.
* Gas formation: The water molecules escape into the air as water vapor (gas).
Boiling point: Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure. At this temperature, the water molecules have enough energy to overcome the forces holding them together as a liquid, and they transition into a gaseous state.
