Increase, but I do not know if the increase will be measurable.
Temperature is a measure of the random motion of atoms and molecules. It is related to the average energy contained in the system.
If water is stirred, the overall molecular motion is increased and this should be reflected in an increase in energy and therefore temperature. Using a hand-crank ice-cream maker, you would never get enough change in temperature to measure. Use two opposing paddle driven by a 10,000 rpm turbo engine and you should be able to see an appreciable difference. The friction between the paddles and the water alone would raise the temperature.

Increase slightly. By stirring the liquid you are speeding up the molecules and adding to their kinetic energy. Thus the temperature would be expected to go up slightly. On the other hand, the stirring motion could faciliate the evaporation of molecules at the surface which would take energy away from the system and reduce the temperature. In the end, you would need a very sensitive measuring device to measure any change in temperature.

The temperature will increase slightly. Stirring the water will cause the molecules of the water to move and in the process they will collide with each other. The motion and subsequent collision will produce heat energy which will be absorbed by the water, thus raising its temperature slightly.

I think that the temperature should increase.
The reason is that when we stir the water, its molecules will collide with each other and this friction will produce heat which will increase the temperature of the water..
In other words, the kinetic energy of the motion gets converted to heat.

It should increase slightly.
The collision of water molecules will cause friction which will produce heat., thus increasing the temperature slightly.

Even the smallest amount of friction will increase the temperature slightly.

rather, there is not any such concern as a wonderfully sealed device. So disrupting the device will reason a launch of power, into the insulation itself and into the stirrer, and at last by using the insulation into our surroundings.

increase slightly, the breakdown and reformation of hydrogen bonds from the jostling would create a slight amount of expelled heat

Okay, me and mah buddy Jeff, we's put a M-80 in his insulated thermos with water in it, and it sploded.

>Increase...if you are putting energy into a closed system then the temperature should rise.<
