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.

Vacuum is empty which has no any molecules to transmit sound wave but not for air, which has molecules to transmit sound waves, this is called medium (air).

What is difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
What difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
How does light change speed from glass to air?
In glass, light will go somewhat slower than in a vacuum. Air is almost like a vacuum, with respect to the speed of light - some difference still exists, though.In glass, light will go somewhat slower than in a vacuum.

Difference between pressure gauge and vacuum gauge?
A pressure gauge measures blow, a vacuum gauges measures suck
Why a vacuum between a panes is better than air?
How would you fit a vacuum between window apnes :) Jokes aside, neither heat nor cold can pass through a vacuum, so you can't lose or gain heat. There's nothing there to transport the thermal energy, whereas in air, there is.

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.

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.
Is there air in a vacuum?
A Vacuum is the absence of air. So no, there is no air in a vacuum.
Is there a difference in cleaning efficiency between a canister vacuum and a broom-style vacuum?
No, the efficiency lies in the suction and brush types.
Difference between pressure gauge and vacuum gauge?
A pressure gauge measures blow, a vacuum gauges measures suck
Will a hot air balloon fly better on high pressure or low pressure?
High pressure. A hot air balloon has a maximum altitude, where it has only just enough lift to keep it there, because there is very little difference in density between hot (near) vacuum and cold (near) vacuum.
What is difference between dry air and atmospheric air?
the difference between dry air and atmospheric air is that atmospheric air contains water vapor but dry air contains no water vapor
