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.

What is the superfluid vacuum theory and how does it explain the fundamental nature of the vacuum in quantum physics?
The superfluid vacuum theory proposes that the vacuum of space is not empty but filled with a superfluid that has unique properties. This theory suggests that particles and forces arise from the interactions of this superfluid, providing a deeper understanding of the fundamental nature of the vacuum in quantum physics.
What letter is used to represent the speed of light in a vacuum?
The letter "c" is used to represent the speed of light in a vacuum in physics equations.
Can you give me a proposal of an investegatory project in physics?
liquid Reppelant Vacuum Broom cleaner
What has the author J Yarwood written?
J. Yarwood has written: 'High vacuum technique' 'Introductory atomic physics' -- subject(s): Nuclear physics
What does the letter "c" stand for in physics?
In physics, the letter "c" typically stands for the speed of light in a vacuum, which is approximately 299,792,458 meters per second.
What type of energy does a vacuum use?
A vacuum cleaner typically uses electrical energy to power its motor, which creates the suction needed to pick up dirt and debris. Vacuum cleaners do not use the concept of a vacuum in physics to operate.
What is an area called where no matter exists?
An area where no matter exists is known as a vacuum. In physics, a vacuum is a space devoid of matter, including particles such as atoms and molecules. This absence of matter allows for the study of fundamental principles in physics, such as the behavior of electromagnetic waves and the nature of particle interactions.
If two people were in a vacuum could they hear each other speak - This is a hypothetical question and assumes a true vacuum.?
No. Yes, provided it is a vacuum that they could survive. A true vacuum in which there is no matter of any kind is a real stretch of physics, and only really exists in theory. What we call a vacuum is really just a strong negative pressure. Matter is still present. Even in the "vacuum" of space, there's still some matter.Answer No. Sound waves will not travel through a vacuum. There is a physics lesson explaining why in detail on this website http://www.physicsclassroom.com/Class/sound/U11L1a.html
What is the space between planets?
We typically consider this space 'vacuum;' however, a newer physics model that ignores the 'renormalization' equations of standard physics is emerging which suggests that this vacuum is actually some 39 orders of magnitude denser than our calculations for a black hole, when the energy inherent in the vacuum is taken into account! Nassim Haramein will explain this 'theory' in the link.
How does the physics of a vacuum enable it to effectively clean surfaces?
The physics of a vacuum cleaner involves creating suction to remove dirt and debris from surfaces. The vacuum cleaner's motor generates a low-pressure area inside the machine, causing air to rush in and carry away particles from the surface being cleaned. This suction force allows the vacuum to effectively lift and trap dirt, dust, and other contaminants from various surfaces.
How does the propagation of light waves in a vacuum relate to the definition of propagation in physics?
The propagation of light waves in a vacuum is the movement of light waves through empty space. In physics, propagation refers to the transmission or spread of waves or energy through a medium. In this context, the propagation of light waves in a vacuum demonstrates the fundamental concept of how waves can travel through space without the need for a material medium.
Is vacuum matter?
In classical physics a perfect vacuum contains no matter.However in quantum physics the Heisenberg uncertainty principle prohibits such a condition, requiring that even a perfect vacuum must contain particles of both matter and antimatter being continuously created and annihilated, each particle existing for only a very short period of time.However in the real world creating a perfect vacuum is as impossible as reaching absolute zero temperature. Thus any practical vacuum will always contain very tiny traces of gas.
