Can liquid water exist in a vacuum?

Liquids will boil whenever the surrounding pressure is less than the vapor pressure of that material. All materials have a vapor pressure, and in a perfect vacuum, the surrounding pressure would be zero. This means that no liquids could remain a liquid in a perfect vacuum.

What happens to water in the vacuum of space?

Water poured into space (outside of a spacecraft) would rapidly vaporize or boil away. In space, where there is no air, there is no air pressure. As air pressure drops, the temperature needed to boil water becomes lower. That’s why water boils much faster on a mountaintop than it does at sea level.

Does water freeze in the vacuum of space?

Key Takeaways: Would Water Boil or Freeze in Space? Water immediately boils in space or any vacuum. Space does not have a temperature because temperature is a measure of molecule movement. After water vaporizes in a vacuum, the vapor could condense into ice or it could remain a gas.

Do stars create water?

Water is abundant in space and is made up of hydrogen created in the Big Bang and oxygen released from dying stars.

How does liquid act in a vacuum?

If you pull a vacuum on a liquid, when the ambient pressure exerted on the liquid falls to the vapor pressure of the liquid at that temperature, the liquid starts to boil. Pulling such a vacuum very suddenly on a sample of water will cause the water to explode violently into vapor by boiling all at once.

How does water react to vacuum?

Water actually boils at a lower temperature if the pressure around it is lowered. In a vacuum chamber, the pressure can be extremely low. So low, in fact, that water can actually boil at room temperature. So, if you put some water in a high-vacuum chamber you will see it boil.

Can water form in space?

Enormous amounts of water, in gaseous form, exist in the vast stellar nurseries of our galaxy. The Hubble Space Telescope peered into the Helix Nebula and found water molecules. Hydrogen and oxygen, formed by different processes, combine to make water molecules in the ejected atmosphere of this dying star.

Can water boil in a vacuum?

In a vacuum, there is no pressure. This is critical for most liquids to remain in a liquid state because with no pressure, the temperature at which they start to boil drops. This means that in the vacuum of space, a cup of water would boil into a vapor before it can freeze.

Will water boil in a vacuum?

In a vacuum chamber, the pressure can be extremely low. So low, in fact, that water can actually boil at room temperature. So, if you put some water in a high-vacuum chamber you will see it boil.

How do stars form water?

Once the hot gases hit the much cooler surrounding material—at about 5,000 times the distance from the sun to Earth—they decelerate, creating a shock front where the gases cool down rapidly, condense, and reform as water, Kristensen said. (Related: “Coldest Star Found—No Hotter Than Fresh Coffee.”)
