it drys things using a vacuum you can make raisins in the sun they will dry in a few days in a vacuum water boils below 0c so there is no liquid involved (sublime) sometimes known as freeze drying if you freeze your grapes they retain their shape but are still raisins vacuum dry is for something like powdered milk where you can heat it too much faster than boiling hi capacity is a big vessel for the vacuum and large pumps
daniel hess' vacuum claner got over $38,000!
Space is not completely empty, but it is very close to a vacuum. The pressure in space is extremely low, with only a few particles per cubic meter. This makes space a very good vacuum compared to conditions on Earth.
Need to know an example price. Which type of vessel.
Use the vacuum cleaner to remove loose dirt from the carpet. OR: The vacuum cleaner works by pumping air out through the exhaust ports and reducing the air pressure within its dust chamber, thereby causing air of relatively higher (atmospheric) pressure to rush inward through the end of the vacuum cleaner's hose to achieve equilibrium, dragging dust and debris with it into the dust chamber. OR: Having extracted as much air as possible from a sealed vessel, the vessel could be considered to contain a vacuum. OR: If one were to enucleate a bubble of 'true vacuum' in normal space, the boundaries of that bubble would expand outward at near-light velocities, essentially obliterating normal space (converting it to true vacuum, wherein matter as we know it cannot exist).
It takes close to 550000
It wouldn't make much of a vacuum leak to cause the engine to idle at high RPM. First check for vacuum leaks even though you may still have good manifold vacuum.
So the deaf have something to complain about too.
The vacuum in a thermos bottle contains very little matter, almost close to zero. The absence of air molecules inside the vacuum minimizes heat transfer via conduction and convection, helping to insulate the contents of the bottle by reducing energy transfer from the surrounding environment.
same as engine vacuum.

Creating a complete artificial vacuum on Earth is challenging due to the planet's atmospheric pressure. One way to approximate a vacuum is by using vacuum chambers that remove as much air as possible. These chambers can be used in scientific experiments and industrial processes to simulate low-pressure environments.
