A diffusion pump works by using a high-speed jet of vapor to push gas molecules out of a chamber, creating a low-pressure environment. The vapor jet collides with gas molecules, transferring momentum and pushing them towards the pump's outlet. This process continues until a high vacuum is achieved in the chamber.

What are the key components and functions of an ultra high vacuum system?
An ultra high vacuum system consists of a vacuum chamber, pumps, gauges, and valves. The main functions of this system are to create and maintain a very low pressure environment, typically below 10-9 torr, by removing gas molecules and contaminants. This is essential for conducting experiments or processes that require a clean and controlled environment, such as in semiconductor manufacturing or surface analysis.
How does an eductor work to create a vacuum or suction effect in a fluid system?
An eductor works by using high-speed fluid flow to create a low-pressure area, which causes suction or a vacuum effect in a fluid system. This low-pressure area draws in fluid or gas from the surrounding environment, allowing the eductor to effectively move and mix fluids within the system.
Has a perfect vacuum been made?
No, it is theoretically impossible to create a perfect vacuum due to the presence of unavoidable quantum fluctuations at the subatomic level. However, scientists have been able to create extremely high-quality vacuums in laboratory conditions.
Diffusion in the states of matter?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration. In gases, diffusion occurs rapidly due to the high kinetic energy of the particles. In liquids and solids, diffusion is slower but still occurs as particles move and spread out over time.
Why do specimens have to be in a vacuum in order to view them under a electron microscope?
Specimens have to be in a vacuum in order to view them under an electron microscope because electrons are easily scattered by air molecules. A vacuum environment provides a clear pathway for the electrons to travel without interference, allowing for high-resolution imaging of the specimen.

Does diffusion go from high concentration to low concentration?
Yes, they move from high, to low.

What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport
WHEn does diffusion occur?
Diffusion is quicker at high temperatures and pressures.
1988 Chevy van idling high at all times?
It could be a vacuum leak. The gasket under the throttle body was known to let go and create a large vacuum leak causing engine to idle high.
What are properties of diffusion?
Moving from an area of high concentration to an area of low concentration(across a concentration gradient) to create equilibrium on both sides.
When was High Vacuum created?
High Vacuum was created in 1957.
Is diffusion faster on heating?
Yes, diffusion is faster at high temperature.
How many pages does High Vacuum have?
High Vacuum has 192 pages.
