Dancing molecules

Boiling is the process of changing a liquid into vapor by applying heat. The molecules gain enough energy, to change from their liquid state and rise as vapor.

Water has its boiling point at 100°C. In a solid state, molecules are stuck in place. In a liquid, molecules can move around, but still are closely associated. In gas, the molecules move around independently and occasionally collide. In a kettle, you can watch the molecules start dancing. Here, I took some pictures documenting the changes until the water starts to boil.
