supercritical
the physical state of oxygen at room temperature is GAS! - Joslyn ;*
difference between critical temp and boiling point
Currently, the superconductor with the highest critical temperature ever recorded is Mercury Barium Thallium Copper Oxide or Hg0.2Tl0.8Ca2Cu3O, which has a critical temperature of 139 K at one atmosphere. This superconductor is a type of ceramic copper oxide and its critical temperature was determined in 1995 by Chakoumakos, Dai, Wong, Sun, Lu, and Xin. Apparently, metal-copper oxide ceramic superconductors have high critical temperatures, which might unlock the key of synthesizing a high temperature superconductor that is superconductive under room temperature conditions.
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.
The temperature at which all the physical states of matter are coexists is called critical temperature. The temperature above that the gas can not be liquefied is called critical temperature of that gas.Gases with high critical temperature are liquefied easily.
Oxygen can be any temperature.
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.
The critical temperature of gasoline is the temperature at which it becomes combustible and varies according to the pressure the gas is under. On average this temperature is 241 degrees Celsius.
A pseudo-critical substance is a mixture of two or more fluids at their joint critical pressures. A critical fluid is a fluid at its critical pressure and temperature. At this point, it is no longer possible to distinguish between gas and liquid, due to the high pressure and temperature.
the temperature which occupied to liquefy the gas at its critical pressure and critical volume ,it is represented by Tc. --------------------------------------------------------------------------------------------- Rafaelrz. The Critical Temperature of a fluid is the maximum temperature at which it's vapor form can be liquefied by increasing pressure. The pressure required in this case is the Critical Pressure of the fluid. At the same time the Critical Pressure of a fluid is the maximum pressure at which you can liquefy a gas by reducing it's temperature. The Critical Point of a fluid is the state of the fluid at it's critical temperature and pressure (The Critical State of the fluid), and the specific volume (m3/kg) or molar volume (m3/kmol) observed, is the Critical Volume (mass or molar). An interesting fact is that at the Critical State, the liquid phase and vapor phase at equilibrium show similar properties.
the critical temperature is for the phase stability? When the phase changes,the energy needed is smaller than the material melton,
the highest temperature at which a substance can exist as a liquid , is called its critical temperature . e.g critical temperature of carbon dioxide is 31.142 degree centigrade .
