What is the conductivity of free space?
Conductivity of free space can be approximated to be equal to the conductivity inside of a vacuum, which is zero.
Is there more pressure used in Osmosis or reverse Osmosis?
Water or liquid move naturally from lower concentration to higher concentration. The drive force is called osmotic pressure. No additional pressure need to drive osmosis process. Reverse osmosis, is apply pressure to fight against osmotic pressure. It do need additional pressure to reverse the osmosis process. It is comparing a zero additional pressure with any positive additional pressure thus of cause reverse osmosis require more pressure.
What is the temperature at which all molecular motion stops?
This is called absolute zero. The temperature is 0 Kelvin or -273.15 degrees Celsius.
When the volume of a substance is zero the substance will exist or not?
There is some debate among theoretical physicists, about whether matter can exist in zero volume. In a sense, this defies belief, since matter exists in space (and time) and if the volume is zero, there is no space. On the other hand, the mathematical analysis of the gravitational collapse of a star into a black hole suggests that the collapse cannot be stopped, and will continue until volume reaches zero and density reaches infinity, creating an object called a singularity, which is unlike normal matter as we know it. This is a difficult subject to research and it may be a long time before we have a definitive answer. But for now, tentatively, I would have to say that yes, you can have a singularity with zero volume and infinite density, and the substance in the singularity does exist.
What is the name of the temperature -273C?
That's called 'absolute zero'.
What is a space that has a pressure of zero pascals?
Vacuum.
In space is air pressure great?
In space, there is no air, and its pressure is Zero.
What is the Atmospheric pressure on Pluto?
Almost zero. Pluto has very little gravity and cannot support much of an environment. In its summer, it can get up to 0.3 Pascals of atmospheric pressure, about 338,000 times less pressure than on Earth.
How much zero gravity is there in space?
Zero! that's why it is called zero gravity!
Does air exist in zero gravity?
If you introduce air into a space where gravity is zero, then air exists there. A current example is the inside of the International Space Station, where the crew live and work in a "shirtsleeve environment" that includes air, pressure, and warmth, but they also live and work in an environment of weightlessness, or what is popularly but erroneously called "zero gravity".
Does pressure on an object affect its acceleration?
A submarine deep in the ocean is under great pressure, and a space capsule outside the atmosphere is under zero pressure. Both of them are capable of high acceleration, zero acceleration, and anything in between. The pressure is irrelevant.
What is zero degrees called?
Zero Degrees Fahrenheit is called nothing. Zero degrees Celsius is the freezing point for water and the melting point for ice, while Zero degrees Kelvin is called Absolute zero. It is the temperature of space. Now, if you mean when water hits the zero degree celcius mark, it's called the freezing point.
What is caused by a transpulmonary pressure greater than zero?
When the transpulmonary pressure is greater than zero water is forced out of the lung tissue and collects in the space between the lungs and the chest wall. This is known as an transudative pleural effusion.
Would you consider atmospheric pressure when finding the pressure of a liquid in a closed container?
pressure is usually measured relative to atmospheric this is called gauge pressure. if you compare against absolute zero pressure (vacuum) this is called absolute pressure.
Why must a astronaut were a pressurized suit in space?
Because in space there is approximately zero absolute pressure, therefore the suit must maintain pressure to allow the astronauts to breath while conducting Extra-Vehicular Activities (EVAs).
Why does the Bourdon gauge not read zero pascals when no pump is connected and the valve is open?
It is because air can still go into the metal tube, and the atmospheric pressure (14.7 psia) will still force the tube to uncoil a bit. But the reading won't be very high.
Definition of pump shut-in pressure?
The definition of pump shut-in pressure is the amount of pressure that is generated by the pump when it is at zero flow, or not flowing. This can also be called "dead head pressure."
