Any temperature below 0 Kelvin or -273.15 Celsius is impossible.

What is the pressure required for natural gas to liquify?
It depends on the temperature!
What temperature does nitrogen liquify?

Why A gas can be compressed but a liquid cannot?
An ideal gas is, precisely, an idealization - a ficticious substance that will NOT liquify, but remain a gas, and have a volume that is exactly proportional to the temperature (at a given pressure). Real gases are an approximation to an ideal gas, under a wide variety of conditions, but at low temperatures, or high pressures, there are discrepancies.
What pressure will condensate drop out of methane gas form and become liquid condensate hydrocarbons?
If you are asking how much pressure you would have to compress methane to in order to liquify it at room temperature, the answer is that methane won't liquify at room temperature. The critical temperature for methane is -87.2 degrees centigrade. Above that temperature it will not liquify no matter how much pressure you apply. At -82.7 degrees centigrade it would take a pressure of 45.96 bar to get it to liquify. See: http://www.chem.purdue.edu/gchelp/liquids/critical.html
How can you get nitrogen out of the air?
by fractional liquefaction, you separate various gasses from air by the temperature they liquify.

How does pressure help in liquefaction of a gas?
Once pressure reaches vapor pressure, gas will liquify at that temperature.
How does pressure and temperature affect gas changing into a liquid?
All gases will liquify (or solidify in some cases) as a result of a sufficiently low temperature or a sufficiently high pressure, or a combination of both.

How does the temperature of a solution affect the speed at which a solid is dissolved?
The higher the temperature, the more movement in the molecules, causing the substance to liquify, or turn to gas, whichever, more quickly than if there were no vibrations in the molecules.
What is the liquefaction point of oxygen gas?
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.
How can you liquify gas?
At 1atm pressure, nitrogen should be cooled below -196C in order to liquify. When it comes to industrial purposes, a higher pressure is usually used as the meting point rises.
How can nitrogen be retrieved from air?
One way is to liquify air using high pressure and low temperature, then fractional distillation to separate the air into its components, including nitogen.
How can you liquify N2 gas?
At 1atm pressure, nitrogen should be cooled below -196C in order to liquify. When it comes to industrial purposes, a higher pressure is usually used as the meting point rises.
How does pressure change the state of a substance?
For example, at a certain temperature a material is a solid - the atoms or molecules hold tight together. If the temperature is increased, the atoms or molecules move faster, and can eventually have enough energy to rip apart. In this case, the substance will change from solid to liquid (or directly to a gas, depending on the circumstances).With respect to pressure: basically, a high pressure changes the distance between the atoms or molecules; this, in turn, affects the forces between them.
