Vacuum.
Since there's no particles present, there's no pressure.
Enthalpy can be zero for a pure substance at its standard state, where it is defined as the enthalpy of formation. This typically occurs at a reference temperature and pressure specified for the substance.
This range can be called "zero to two" or "between zero and two."
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.
This is called absolute zero. The temperature is 0 Kelvin or -273.15 degrees Celsius.
Vacuum.
In space, there is no air, and its pressure is Zero.
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.
Zero! that's why it is called 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".
it is either zero or very, VERY near zero. A zero air pressure implies there is no atmosphere. Phobos is merely a captured asteroid, these objects are too small, not enough mass, to be capable of a large enough gravitational field to maintain an atmosphere.
The temperature at which an ideal gas occupies zero pressure is called absolute zero. It is defined as 0 Kelvin or -273.15 degrees Celsius. At this temperature, the particles in the gas have minimal kinetic energy and do not exert any pressure.
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.
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.
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.
The vacuum pressure of space is extremely low, close to zero. This lack of pressure can impact celestial bodies by causing gases to expand and escape, affecting their atmospheres and surfaces. Additionally, the vacuum of space can lead to the freezing and desiccation of materials on celestial bodies.
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."
