Yes. The process is similar to any of these other ones:
-- Convert the emptiness inside a plastic bottle into hydraulic pressure,
by pumping water into it.
-- Convert silence into cacophony by means of a klaxon, two tubas, and
a firecracker.
-- Convert ice into boiling water by means of added heat.
There is no pressure in a vacuum, a vacuum is the absence of anything, there is nothing there to push. Air from a pressurized space that becomes open to a vacuum may push you into the vacuum, but the vacuum itself does nothing as it is literally nothing.
subtract 0.0011 from the density in vac to get density in air.
In case they're exposed to a vacuum
A Vacuum is the absence of air. So no, there is no air in a vacuum.
No. First of all it wouldn't stay on the ground. and why would you need to vacuum?A vacuum cleaner depends on a difference in air pressure to operate. With no air pressure in space, there could be no difference in air pressure and thus no operation.Inside a manned spacecraft, which is usually pressurized a vacuum cleaner will obviously work just fine; especially for collecting and disposing of water globules. Also the standard NASA space toilet uses a modification of a vacuum cleaner for urine collection.
It is not pressurized. A breather valve at the fuel tank allows fuel vapor to flow out of the tank and be stored in a charcoal canister until it is drawn into the intake of the engine. It also allows fresh air into the tank to prevent a vacuum. The fuel cap is not vented, all air moves through the breather valve. Technically it may, at times, be pressurized or have a vacuum. However, a properly functioning vapor system should limit that to a max of .725psi, or a vacuum of .45in. Hg.
that the can contained pressurized air.
Yes, because the entire system de-pressurized when you added a new component to the system.
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.
No. If anything, it'll be the other way around. The pressurized bottle is a little heavier, and will float lower.
Yes, the plane is pressurized.
At the high altitudes which airliners fly in, there is less dense. Since air is good for us humans, the cabin is pressurized in order to provide enough air to breathe.
