## Where is absolute zero pressure attained?

The condition of perfect vacuum, i.e., absolute zero pressure can be attained at. a temperature of – 273.16°C.

### How is absolute zero defined?

Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.

**Can we achieve zero pressure?**

Fluids push rather than pull, so the smallest absolute pressure is zero. (A negative absolute pressure is a pull.) Thus the smallest possible gauge pressure is Pg = −Patm (this makes Pabs zero). There is no theoretical limit to how large a gauge pressure can be.

**What is absolute zero derive it?**

Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvins.

## What is the value of absolute zero pressure?

Absolute zero is the temperature at which the gas’s pressure equals zero.

### What does it mean when pressure is 0?

Absolute pressure is the measure of pressure with respect to absolute zero pressure, which is the pressure of a perfect vacuum. The absolute pressure measurement is required for the ideal gas law in the same sense that temperature must be represented by its absolute unit, the Kelvin.

**Is 0 Kelvin possible?**

Summary: On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin. At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears.

**Is there an absolute hot?**

But what about absolute hot? It’s the highest possible temperature that matter can attain, according to conventional physics, and well, it’s been measured to be exactly 1,420,000,000,000,000,000,000,000,000,000,000 degrees Celsius (2,556,000,000,000,000,000,000,000,000,000,000 degrees Fahrenheit).

## Is space at absolute zero?

If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit). But space is mostly full of, well, empty space.
