what causes it to boil why does water bubble when it gets to a certain temperature.

Air molecules exert pressure on the surface of the water molecules, this reduces the momentum of the atoms within the water.
(Naturally without any external pressure on water, the water would normally bounce into each other and evaporate into a gas). It is because we have air pressure which allows water to behave as a fluid
.
Therefore more energy (heat) is required before the water molecules are able to move freely (boil) and break free into a gas (evaporation).
Because more energy is required, often this is transferred to the water molecules as heat.
As we climb higher into the mountains, the air pressure reduces gradually. Therefore there is less air molecules exerting pressure on the surface of the water. On the surface of a mountain, a climber is able to boil water at a much colder temperature (less than 100 degrees).
If we continue to climb above the mountains and into space, at some point water is able to boil at any temperature. This is because there is no external force (air) exerting on the water. And the water is able to vibrate move freely in the form of a gas.
Just because the water boils at a less temperature above sea level doesn't mean that water is hot.

The molecules in the water contract and become very close and basically it's like when you rub your hands together and they heat up, It's the same concept as that. As far as what really makes it bubble I really can't remember, I'm going through the files from grade school, lol. I would imagine the molecules become tight, combine and rise to the top, basically boiling point is so hot the molecules are moving so rapidly.

Heat increases kinetic energy and is able to boil water at a specific temperature. Boiling is part of the process of the water molecules having so much energy that they can't be contained in their liquid form and escape as a gas.
