If we take a water bottle to moon and opens it there then what changes will take place in water ??

Question

changes are.
1-it will become hot
2-it will become cold
3-dissolve in co2 & o2
4-no change

Answer 1

It will boil and evaporate in an instant.

Answer 2

2

Answer 3

Answer 4

My daughter all started dozing 6 hours at 6 weeks, 8 hours round 14 weeks. She's 4 a million/2 months now and sleeps 11 hours (9pm to 8am) do not problem, all little ones are diverse. My cousin has an 11 month old that still wakes up each 3 hours at evening. i got here across that acquiring right into a night time recurring helps a lot. Play for a touch, bath, jammies, bottle and then mattress. That recurring worked tremendous with my daughter. We do it each evening and we haven't had a foul evening yet. do basically not problem, earlier you know it he will be dozing by. sturdy success and congrats.

Answer 5

5 - None of the above.
Assuming that the temperature of the bottle of water is above the triple point temperature, around 32 F, the contents will vaporize quickly. It can do so while its temperature remains the same. If the temperature is below the triple point temperature, the water may solidify first, then go to the gaseous phase. It would depend on the actual path of the process, which is determined by constraints imposed during the process.

Answer 6

The obvious answer seems to be 2-it will become cold.
The sealed nature of the water bottle means that it is free from contamination by other particles and elements; that does not mean, however, that the bottle can prevent energy loss. In fact, the water is moving from a sealed environment w/ energy (earth sealed by ozone layer, trapping sunlight energy) to an environment with virtually zero energy (outer space.) There, energy will flow out of the water system in an attempt to balance out the deficit of energy outside the water bottle. Therefore, if the water loses energy, the hydrogen- bonds of the water molecules will begin to strengthen because the water molecules get closer together, and it eventually forms a solid.
What's up with 3?
Assuming that it is, in fact, carbonated water (which is not mentioned), the formula would still be H2CO3 + H2O. The covalent bonds of the carbonic acid will not "break" due to the loss of temperature.

Answer 7

I consider that neither of the choices hold true. Rather an alien option that is " vaporisation " 'll be observed. It's so because, the moon is void of an atmosphere. As such, no air and resultantly no atmospheric pressure. Now u may well recall that as we take water to greater heights, its b.p. decreases. This is due to the reducing atmospheric pressure.
Now, if the atmospheric pressure is 0 (as on moon), water is liable to vaporise.

P.S. : I mean vaporise (a pressure related phenomenon), not evaporise(concerned with temperature)

Answer 8

The temp. of water will not change rapidly. the water will evaporate in no time. when the water will come out of bottle it will be exposed to radiation from sun and it will start disintegrating into H and OH radicals (and not in CO2 and O2 neither in H+ and OH- ).in this way the water will escape the atmosphere of moon.

Answer 9

hot or cold depends on the temp but when bottle is opened the liquid strictly takes spherical shape n floats in space(moon)..since the gravitational force is very less the surface tension is more hence it strictly takes a spherical shape....chemically there may not be any change

Answer 10

The water will start to evaporate fast (because it is vacuum there), and the heat of vaporization will be taken from the water itself. So it will become cold

Answer 11

Whered you get Co2 from?. I think the oxygen in the water would expand and instantly evaporate, and the remaining hydrogen would dissapear too.
