How does a straw work?
As you create a partial vacuum in the top part of the straw, the weight of the entire atmosphere above the glass applies a pressure of 15 PSI on the liquid surface. This pressure pushes the liquid up the straw until the pressure in the straw returns to 15 PSI too. If you keep creating the partial vacuum the air pressure will push the liquid all the way to the top of the straw and out.
What make suction cups stick?
A partial vacuum between the compressed suction cup and the flat surface.
When did Daniel Hess invent the vacuum cleaner?
Daniel Hess invented the vacuum cleaner on July 10, 1860. He was indeed the first to create the vacuum cleaner.
How can you create a vacuum?
Very short term: create an explosion, in a safe area. Long term: settle on a fixed small sized suitable area and suck the air out until the vacuum is no longer needed.
Why when you suck a air of a bottle it shrinks?
When you suck air from a bottle you create a partial vacuum and there is less air pressure in the bottle; but outside there is atmospheric pressure so it tends to collapse the bottle.
How does a water aspirator create partial vacuum?
no
Can you create vacuum with the help of electric and magnetic fields?
Normally you create vacuum by pumping out the air from a sealed container. Electric and magnetic fields would seldom be used, unless you had some electrically charged particles that you wanted to remove from your partial vacuum.
What is the adjective of vacuum?
of containing, producing, or utilizing a partial vacuum
What is air with few particles called?
a partial vacuum
Where is a place where molecules are far apart?
The Answer is rarefaction.
What is a vacuum in physics?
A system is said to be at a partial vacuum if it is at a negative pressure (pressure less than atmospheric pressure). When you use a straw, the partial vacuum created inside the straw is what causes your drink to travel up the straw and into your mouth.A perfect vacuum would be a space with nothing in it and a temperature of 0 degrees kelvin. Practically, however, we can only achieve and work with partial vacuums or pressure differentials. Even what we call outer space is only a partial vacuum. Rule of thumb: Nature hates a vacuum.

Is a light bulb evacuated?
Yes, the inside of a light bulb is a partial vacuum.
Can a vacuum cleaner work in a vacuum?
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.
Can two magnets create a vacuum?
No
What is a vacuum and a partial vacuum?
Vacuum is measured in inHg or inches of mercury and a true vacuum is anything below zero on this scale...for reference normal atmospheric pressure or air pressure is about 14.7 inHg so anything less than that could be expressed as a vacuum or less than atmospheric pressure if above zero but less than 14.7 inHg...you can measure this with a vacuum gauge that you can get at any autoparts store but you can feel a vacuum as a suction just like your vacuum cleaner....So a vacuum is anyththing zero inHg or below and a partial vacuum is anything between zero and 14.7 inHg.
How does a narwhals get its food?
Narwhals create a sort of vacuum and sucks up its food
