Vacuum refers to a volume of space that is essentially empty of matter,such that is gaseous pressure is much less than atmospheric pressure. while AIR is the mixture of oxygen, nitrogen,and other gases that are consistently present around us.

What is the difference between a vacuum cleaner and a vacuum?
A vacuum cleaner is a machine used to clean floors by sucking up dirt and debris, while a vacuum refers to a space devoid of matter or air.
What role does pressure play in the functioning of a vacuum?
Pressure plays a crucial role in the functioning of a vacuum by creating a difference in pressure between the inside and outside of the vacuum. This pressure difference allows the vacuum to suck in air or other substances, creating a low-pressure environment inside the vacuum.
How does light change speed from glass to air?
Light changes speed when it moves from glass to air due to the difference in optical density between the two mediums. In glass, light travels slower due to the higher density, resulting in refraction as it enters the less dense air. This change in speed causes the light to bend and change direction.
What is difference between density in air and density in vacuum?
Density refers to the amount of mass per unit volume. In air, there are molecules present which contribute to the overall mass and density. In a vacuum, there are no molecules present, so the density is essentially zero.
What causes the suction of a vacuum?
The suction of a vacuum is caused by a difference in air pressure inside the vacuum cleaner compared to outside. A motor creates a low-pressure zone inside the vacuum, causing the higher-pressure air outside to push debris into the vacuum cleaner.

What is the difference between a vacuum and a Hoover?
Spelling.
Is there any difference in speed of a light in air and vacuum?
Yes, but it is only a slight difference.
How does a magnet respond in a vacuum?
Pretty much the way it responds in air. There is little difference between the ability of the magnetic lines of force to "penetrate" and "travel through" air as a vacuum. The "field strength" and "field pattern" will be virtually identical.
How does light change speed from glass to air?

What is the difference between Air circuit breaker and Vacuum circuiut breaker?
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
What causes the suction of a vacuum?
The suction of a vacuum is caused by a difference in air pressure inside the vacuum cleaner compared to outside. A motor creates a low-pressure zone inside the vacuum, causing the higher-pressure air outside to push debris into the vacuum cleaner.
What is the main difference between mechanical and electromagnetic waves on Jiskha?
The main difference between mechanical and electromagnetic waves is how they travel. Mechanical waves require a medium, such as air or water, to propagate, while electromagnetic waves can travel through a vacuum.
What difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
Is there air in a vacuum?
A Vacuum is the absence of air. So no, there is no air in a vacuum.
