What else can I help you with?
Where was vacuum tube was made?
who made the vacuum tubes
Which are not the best conductor?
A complete vacuum.
Does matter exist in a complete vacuum?
The matter exists in everywhere, include the vacuum.
Have scientists ever made or created a complete vacuum or observed one in nature?
No is the short answer. There is probably no complete absence of atoms anywhere. As to how well scientists do in the lab, in vacuum spectroscopy, vacuums of the order of 10-16 mm Hg can be achieved. Probably CERN do better. [The curious measurement in mm of mercury of vacuum still is used.]
What is the scientific term for a state of complete emptiness?
Perhaps "complete vacuum" or "hard vacuum" or the "vacuum of deep space" will suffice. Even in the vast "nothingness" between galaxies there is going to be an atom or two of hydrogen floating about. That's about as good as it gets. But if a state of complete emptiness is desired, a "perfect vacuum" is what the seeker may be looking for.
What is volume without mass?
A vacuum. However, a complete vacuum is impossible due to quantum effects.
Example of no matter?
A complete vacuum contains no matter.
What is a vacuum made of?
A vacuum is composed of empty space.
Does heat exist in a vacuum?
No. Heat is a measure of molecular energy in matter, a true vacuum would not contain matter. However, since there is no such thing as a complete vacuum, then Yes.
what is a cheap central vacuum?
The Electrolux PU3450 Central Vacuum is probably the cheapest vacuum ever made.
Do tornadoes have air inside them?
Yes. A tornado is pretty much made of air. Although pressure inside a tornado is low it is nowhere near being a complete vacuum.
A complete absence of matter is a?
nothing??? im guessing.. :P
