What will happen to a jug of water if it is left on the moon unattended? Will we get a pure bacteria free water?

it will be stolen immediately, water is rare in moon!

Because the moon's surface is alternately heated then cooled when in sunlight or darkness, it will always remain at a temperature well above the background temperature of outer space and well above absolute zero temperature (unlike a comet at the fringes of the solar system?). In the sunlight the water will boil. In the the darkness the water will freeze but moon energy will cause it to sublimate (evaporate without becoming a liquid), especially in a near-perfect vacuum. Certain bacteria may be killed by the intense heat or the lack of water. However the DNA of bacteria and viruses likely would remain intact because they are chemical molecules. If exposed to the sun's unfiltered UV (ultraviolet) rays it is likely that even DNA will be at least partially destroyed.

It depends on where you leave it. If it's on the dark side of the moon, the water would freeze very quickly. Any bacteria that might be in the water would be frozen inside. Depending on the bacteria, that could preserve them almost indefinitely. Other forms of bacteria would be destroyed by the freezing process.
If left on the bright side of the moon, the water would boil out of the jug, since the surface temperature of the moon is over 100C in daylight. This temperature would kill almost any bacteria. Those that could survive the extreme temperature would eventually die out for lack of food.

No as the pressure on the moon is zero it will boil initially and then freeze due to the cooling effect of evaporation after that it will sublime.
Certainly if it had bacteria in it they would not be killed immediately.

It would vaporize.
On the sun side of the moon, it would "boil" immediately
On the dark side, it would freeze, breaking the jug (whops, hope they won't miss that), and when the sun his it would boil off.

i think it would float away. As for the bacteria... wouldn't they be able to survive in the water, because it'll still have hydrogen and oxygen right? It wouldn't last forever though... you know... when the sun got on it.

Surely it wouldn't be a jug of water, as it would be floating off into space?????

Yes. The moon IS lifeless, it's Mars that might be up for debate ;)

water in moon will evaporate. moon is believed to have no atmosphere.

It would freeze and the bacteria would die
