Can you create a vacuum in space?
vacuum, space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there. A vacuum can be created by removing air from a space using a vacuum pump or by reducing the pressure using a fast flow of fluid, as in Bernoulli’s principle.
Why is space not a perfect vacuum?
So, what is a vacuum, and why isn’t space a true vacuum? By definition, a vacuum is devoid of matter. Space is almost an absolute vacuum, not because of suction but because it’s nearly empty.
Why is the atmosphere and the space around you not considered a vacuum?
Because outer space has very low density and pressure, it makes something very close to a vacuum — but it’s still not a perfect vacuum. Even in interstellar space, there are still a few hydrogen atoms in every cubic meter.
How can a vacuum exist next to a non vacuum?
Originally Answered: How can a vacuum (space), exist next to a non-vacuum (Earths atmosphere) without a barrier? A vacuum only exists because it is the absence of any and all matter. All matter in the universe is miniscule in size compared to the universe.
How is vacuum created in condenser?
Water is used to condense steam back to liquid water in any form of boiler system, whether on board ship or in power plants. In other words, the specific volume of water at a given pressure is many times lower than that of steam. This enormous reduction in volume creates the vacuum inside the condenser.
Does a vacuum have air resistance?
Air Resistance. When an object falls with air resistance, both its acceleration and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum.
How is vacuum generated?
In general, a vacuum is created by starting with air at atmospheric pressure within a chamber of some sort. As molecules are removed, there are fewer other molecules for a given molecule to collide with the distance becomes longer and longer as the pressure is reduced.
