(I suppose that you mean supercritical state of fluid.)
Supercritical state of liquid-gas is a state that liquid state and gas state stop to exist at particular temperature and pressure.
There is only just fluid state which has both liquid and gas property and if you change the pressure or temperature just a bit, it will change to one of the state.
How to achieve supercritical state ?
The supercritical state is done at HIGH TEMPERATURE and PRESSURE.
For example, the famous CO2 fluid (used to separate caffeine from the coffee bean) is acquired at 304.1 Kelvin and 72.8 atm.

Principles of Super Critical Liquid Extraction?
Supercritical fluid extraction is a process that uses supercritical fluids, such as carbon dioxide, to extract solutes from solid or liquid samples. The main principles include the use of a supercritical fluid as the solvent, which offers benefits such as tunable solvating power, high efficiency, and minimal residue in the extracted material. The process involves applying high pressure and temperature to the supercritical fluid to reach a state where it exhibits properties of both liquids and gases, making it highly effective for extraction purposes.
Is supercritical fluid a matter?
Yes, a supercritical fluid is a state of matter that exhibits properties of both liquids and gases. It occurs when a substance is heated and pressurized above its critical point, resulting in a phase where it can diffuse through solids like a gas but dissolve materials like a liquid.
What is supercritical fluid chromatography?
Supercritical fluid chromatography is very similar to high pressure liquid chromatography (HPLC), however the mobile phase exists in a supercritical state. To refresh your memory, recall that super critical fluids exist at temperatures and pressures higher than a substances critical point. This means that the fluid acts as both a gas and a liquid. For example, a supercritical fluid may pass through substances like a gas, but also dissolve substances like a liquid. Why do supercritical fluids exist? Well, the temperature is high enough that the molecules cannot exist together as a fluid because they have too much energy to stick together. However, the pressure is too high for the molecules to have a root mean square distance sufficient enough to exist as a gas. SFC exploits this property, using a supercritical fluid to dissolve the chemical in question into the fluid, but move it quickly in the gas phase. Heavy molecules travel slower, while light molecules travel faster, thus causing separation. In addition, chiral molecules can be separated via this method.
What type of solvent is carbon dioxide?
Liquid carbon dioxide (supercritical CO2) is used as solvent.
What is the critical temperature and pressure of diesel?
The critical temperature of diesel is typically around 550°C, and the critical pressure is around 80 bar. At these conditions, diesel would exist in a supercritical state, with properties of both a liquid and a gas.
Is liquid nitrogen a supercritical fluid?
No, liquid nitrogen is not a supercritical fluid. A supercritical fluid exists at a temperature and pressure above its critical point where it displays properties of both a liquid and a gas. Liquid nitrogen remains in the liquid state at low temperatures and normal pressures.
Is Saturn mostly solid?
No. Saturn consists mostly of supercritical hydrogen and helium, in a state between liquid and gas.
Is there any application of supercritical fluid extraction in refinery?
Supercritical fluid extraction is now used in laboratories.

Why is nitrogen not used in supercritical fluid extraction?
Because at room temperature it behaves like gas. Although it is in supercritical state, its density becomes very low on temperatures far above critical value, so it behaves like gas and it's not useful for extraction.
What change(s) in physical state occur if carbon dioxide at 50C and 73 ATM is cooled to -78C and 73 ATM?
The carbon dioxide would change from a supercritical fluid state to a liquid state as it is cooled. At 50°C and 73 ATM, carbon dioxide is in its supercritical state, which means it possesses properties of both a gas and a liquid due to high temperature and pressure. By cooling it to -78°C while maintaining 73 ATM pressure, it would transition into a liquid state.
What are the unique properties and applications of supercritical nitrogen in various industries?
Supercritical nitrogen is a state where nitrogen is at high pressure and temperature, exhibiting unique properties like high density and solvating power. It is used in industries for processes like extraction, purification, and as a solvent due to its ability to dissolve a wide range of compounds.
What is meant by supercritical andhow dose it relate to making a nuclear bomb?
subcritical - a mass or arrangement of fissionable or fissile material unable to sustain a neutron chain reaction. It can provide a fixed amount of neutron multiplication from a neutron source, but after removal of the neutron source the chain reaction rate drops exponentially.critical - a mass or arrangement of fissionable or fissile material capable of sustaining a constant neutron chain reaction. No increase or decrease. (Nuclear reactors operate at critical)supercritical - a mass or arrangement of fissionable or fissile material capable of not only sustaining a neutron chain reaction, but once initiated the chain reaction rate rises exponentially. (Nuclear fission bombs explode when made supercritical)A nuclear fission bomb must have 2 of these states: subcritical (so that it can't explode until desired) and supercritical (so that it explodes with an effective yield). This requires a rapid "assembly" system using conventional explosives to rearrange the fissile material from subcritical to supercritical in about 1ms. A neutron source starts the chain reaction and the explosion completes in about 1 microsecond.
Where are the supercritical boilers installed in India?
Bharat Heavy Electricals Limited (BHEL) has despatched boiler columns for the first supercritical boiler, being manufactured in India. These columns will be used for installation of BHEL-built supercritical Boilers at Barh Thermal Power Project Stage-II, located about 75 kms from Patnain Bihar
What does the acronym SFIA in a refinery mean?
Supercritical Fractionation and Isomerization Area
Can a gas act as a nonpolar solvent?
Supercritical carbon dioxide is used as a non polar solvent to extract caffeine from coffee beens. Supercritical gases are not quite gases and not quite liquids but sort of in between.
