When water boils, the bonds holding the water molecules together as a liquid (intermoleular forces) are broken, and the molecules are allowed to escape as a gas (vapor, steam). So, this is simply a change in state, or a physical (not chemical) change.
When a liquid is heated, the particles are given more energy. They start to move faster and further apart. At a certain temperature, the particles break free of one another and the liquid turns to gas. This is the boiling point. The boiling point of a substance is always the same; it does not vary.
The thermal energy transforms into kinetic energy.
Think about it. If you touch cold water, it feels cold because the atoms are moving slowly. However, if you touch hot water then it feels hot because the atoms are moving all over and colliding with your fingers.
A change of phase: from liquid water to gaseous (vapours) water.
It boils
Water boils at 212 degrees Fahrenheit
Water boils at 100 degrees Celsius.
it gets hot
Assuming they are non-volatile, solids in liquid water will remain in the water when it boils. This is the process of distillation, where the solids and non-volatile matter is separated from the water, and is left behind as the water evaporates off.
The water becomes a gas.
Water IS a polar molecule.

Water boils at that temperature.
nothing special, BUT at 0oCelsius, water freezes .....and at 100oCelsius, water boils
Water boils at 212 degrees Fahrenheit
At 212 oF, water boils at 1 atm of pressure.
Water boils at 100 degrees Celsius.
It boils and becomes steam.
