shaking water to heat it?

Question

If the energy that is expened in shaking water in a closed bottle is turned into heat,, could we boil water by shaking it fast enough?

Answer 1

Yes.

However in normal situations the energy would be lost through the transfer of heat through whatever was shaking the water as the amount of energy transferred through would be very small.

However, if the water was in a vacuum and being shaken without physical contact (ie, with an alternating electromagnet acting on an iron water container). it would be possible to boil the water after a long period of intense shaking.

Answer 2

Temperature is the measure of the average kinetic energy of the particles of a system. The faster the particles are moving, on average, the higher the system's temperature.

You could certainly raise the temperature of water by shaking since you would be increasing the water molecules' average kinetic energy.
Simply raising the water's temperature to 100 degrees C is one thing, but while the water is boiling, one must over come the latent heat of vaporization of the substance.
All the while as the water boils, energy is being supplied to overcome the latent heat of vaporization, the temperature of the water is constant, all the heat energy goes into overcoming the attractive forces within the substance.
Only after the liquid water boils into steam can a further increase in temperature be achieved.

Answer 3

Yes. The water will heated up.

Answer 4

Absolutely. You could even apply enough energy to make the water fuse into new elements (good luck). Humanity isn't even close to this but nature can and does.

Answer 5

Theoretically it is possible, but the container the water is in would have to be well insulated, otherwise the water would lose heat as fast as it is created.

Answer 6

Certainly, but boiling requires very vigorous shaking and thermal insolation to prevent heat loss.

Answer 7

yes it will
