Do speakers work in a vacuum?
Sound waves can even travel through solids! Even if the vacuum is not perfect, the sound of the speaker will be greatly lessened because there are fewer molecules of air for the speaker to compress, and the molecules are so far apart that they do not interact strongly among one another.
What happens when air enters a vacuum?
5 Answers. It will diffuse into space. Space is a near-perfect vacuum — its pressure is nearly zero and it has extremely little matter (in the empty parts, at any rate). Once there, it creates a localized blob of air, with low pressure — but not as low as the surrounding space.
Where does air go in a vacuum?
Vacuums never “suck” air. What they do is present an empty space and then air pressure forces the air into the vacuum. Air pressure is not uniform throughout the atmosphere. The lower the altitude, the higher the air pressure; thus, as you move higher, the air pressure decreases.
How fast does air fill a vacuum?
Air molecules move QUICKLY. At 20°C, an average air molecule will probably move around 500 meters per second. When they bounce off something, they push off that thing, they impart some momentum. The force experienced by an area with a lot of air molecules bouncing off it is air-pressure.
Can oxygen exist in a vacuum?
You breathe it every minute, but there’s hardly any molecular oxygen—otherwise known as O2—in space. In fact, astronomers have detected interstellar molecular oxygen in only two places: the Orion Nebula and the Rho Ophiuchi cloud. …
Can you breathe Monatomic oxygen?
Monoatomic Oxygen is unstable and only exists in a high energy environment like a plasma. I don’t imagine breathing a supercharged plasma would go well. Even if you could find a way to breathe O it would cause cellular damage and likely kill you.
Can you breathe in Nebula?
Could a star exist with this cloud similar to earth atmosphere around it where a person could breathe without much effort? Nope. The solar wind and radiation pressure and a combination of planetary and stellar gravity would either blow away or hoover up all the gas cloud in relatively short order.
