After water falls down a waterfall the water's temperature increases, the potential energy is converted into kinetic energy, friction between the earth and the water heat the water, this is a similar relationship when water falls on a hydroelectric turbine except some of that kinetic energy is converted into electric energy.
When you shake a well insulated container of water, it is similar to water continuously falling, the energy has no where to go except back into the water, therefore raising the temperature, with a perfectly insulated container the water's temperature will continue to rise with agitation and it will eventually boil.

Boiling is what happens to water when it is heated and begins to move into a gas state. The bubbles you see forming in it are gas bubbles, and when they break the surface of the water, they release steam, which is water in it's gas state.
Shaking water, with no heat, also causes bubbles, but those are just regular old air bubbles, not water vapor bubbles. The water is not boiling, it is just being agitated, and air from the container it is in are moving down into the water and making it bubble. Water does not boil, and turn into vapor or gas state, without the application of heat.

Is this related to the definition of boiling? Because technically when something is excited and tumultuously moving I guess it is technically boiling so it doesn't necessarily need "heat" (heat is essentially just movement).
The shaking provides enough energy to exceed its boiling point so to speak.

i don't have full details. and im not sure it BOILS, you need lots of heat for that. but it guess its because you are increasing the entropy or degree of disorder. also you are SHAKING it, the energy you are using to shake it is being absorbed by the water molecules. when the molecules absorb energy, their kinetic enegy increases, increasing collisions with other molecules and that produces energy. or heat. look up charles law why increasing temp goes with increasing molecular activity and volume, justy relate the concepts. my explanation is quite jumbled, just trying my best. hehe good luck!

The stucture of liquids is unstable unlike solids. The molecules of the water rub together with each other and the container and that is what creates the heat.

I believe it is because of friction but that would just be a guess

it does not boil, it reacts with the air only

Does it boil or bubble? Bubbles are from air.
