What happens if an astronaut pours a pint, quart, or gallon of water or any liquid, into outer space?

Question

He would use a device that would pour the water out into space. What would happen to that water? Has NASA done this yet?

Answer 1

it would form a sphere and float around

Answer 2

When you pour any liquid, this pouring occurs due to gravity. Gravity is the force that makes "pouring" work. In outer space, there is no gravity (or, atleast not like what we see on Earth) and so you cannot pour any liquid into outer space.

If you use a pump of some other device to expel water (or, any liquid) into outer space, the liquid will be bombarded by cosmic radiation, and solar radiation (if sun is nearby). Depending on the intensity of the radiation, the liquid could evaporate or freeze or stay a liquid.

Answer 3

I must assume that you mean have they poured it out inside the shuttle. If they poured water into space it would evaporate, possibly explosively. However, since there is enough air pressure in the shuttle to keep water in liquid form, they have indeed put water into a microgravity environment. It forms globs that stick togehter by thier own surface tension, and wiggle like jello- while they float and settle down.

Placed directly into space, water would not freeze. Space is not cold as many people think. Space itself does not have a temperature. In the sunlight above the earth it is possible to silmultaneously fry and freeze as your body radiates away heat on one side and absorbs solar light on the other.

Cosmic radiation and heat from the sun have very little to do with the effect that water would simply evaporate. The boiling point of water depends on the pressure of the air above it. No, air, no pressure, water boils away nearly instantly.

The amount of water would only affect how quickly the water evaporated.

Answer 4

ultimately, a sensible answer! i will 2d it. The decrease the rigidity, the better the temperature water boils at. area has NO rigidity. So the water will spontaneously boil till it reaches its severe element, at which element it is going to freeze. At this element, I especially doubt that's one continuous mass. it is going to likely be spread out as alot of (now-frozen) globules. it truly is the instant reaction. i assume the UV will chop up the bonds finally, too. As for the oxygen, assuming it really is a gas once you launch it, no longer something seen. it's going to spread out ad infinitum.

Answer 5

It would freeze instantly verry cold in space

Answer 6

First it will form a spherical ball and then it will begin quickly boiling away into gas.

Answer 7

it freezes and turns to gas
