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 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.
The critical temperature of a gas is the temperature at or above which no amount of pressure, however great, will cause the gas to liquefy.
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.
As pressure increases the temperature required to vaporize water is less. So with increase in pressure there is decrease in temperature required to boil so latent heat also decreases.
18.6 ATM for diesel UDER ATMOSPHERIC PRESSURE AND TEMPERATURE.
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.

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.
It liquefy the gas at its critical temperature
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.
Above Critical Pressure. This will depend on the gas and its temperature.
the temperature and pressure where the liquid state no longer exist is called the critical point
the temperature at which a gas can be liquified by lowering the temperature which is accompanied by applying pressure.
The total entropy of steam at critical pressure and temperature is equal to 1.0785 btu/lb. (as liquid water does not exist at critical pressure and temperature the entropy of liquid is 0) *from Elementary Steam Power Engineering, E. McNaughton, 1923
The critical temperature of a gas is the temperature at or above which no amount of pressure, however great, will cause the gas to liquefy.
