What happens if you let air out in space?

There’s no pressure in space, so air expands and would painfully tear through the tissue of your lungs as this happened. In an extreme environment like space, it would only take about 15 seconds for your body to use up all the oxygen in your blood. The second that deoxygenated blood reached your brain, you’d pass out.

What keeps the vacuum of space from Earth?

Gravity pulls on the atmosphere, compressing it, and creating pressure. If we could magically turn off gravity then the atmosphere would be released from that compression and spring away from the Earth. So, at the root of it, gravity is the thing that keeps the atmosphere near the surface.

What happens to oxygen in the vacuum of space?

So, if the sealed container is opened up in space, the oxygen would quickly leak out, because the molecules near the vacuum edge would be instantaneosuly kicked out by the gas innermost molecules. This would happen rather quickly and in a chained manner, but is dependent on the size of the open hole.

How do you get air out of a siphon tube?

Immerse the tube in a container of water. Coil the siphon tube into a circle and place it into a container full of water. Gently push the tube down until it is completely covered. You will see air bubbles pop up to the surface of the water, as the air escapes from the inside of the tube.

What happens to the level of air in a siphon?

If you were to evacuate all of the air in the tube, the level inside would rise to a level equal to the atmospheric pressure pressing down on the surface of the container. The traditional explanation of a siphon states that the flow in the down leg, due to gravity, creates a partial vacuum in the upper most portion of the conduit.

How do you move water through a siphon?

If you are working with fresh water, it’s possible to move water through a siphon using pressure from your mouth. If you are working with a single siphon tube, submerging the tube and draining it is a quick option. However, if you are tackling a larger job, then a two-hose siphon system might be your best bet.

How to siphon water from a full bucket to an empty bucket?

So, if you are siphoning water from a full bucket to an empty bucket, place the destination bucket on a stable, lower surface. Position the tube. Stick the end of your siphon tube into the empty destination bucket. It should almost reach the bottom of the bucket to prevent it from coming back out.
