For example from hydrogen critical point (-239,85 0C) to lithium critical point (2 950 0C).
Critical pressure is important because it is the pressure at which a substance transitions between liquid and gas phases at its critical temperature. It represents the maximum pressure at which a substance can exist as a liquid, and is crucial for understanding phase behavior and designing processes such as distillation and extraction. Critical pressure is also used to define the critical point of a substance on a phase diagram.
Pseudo critical pressure and temperature are values used to determine the compressibility factor of a gas. They are calculated based on the critical properties (critical temperature and critical pressure) of a gas and are used in the generalized compressibility chart to determine the compressibility factor. This factor helps in predicting the behavior of a gas under different conditions.

Temperature refers to the measure of thermal energy present in a substance, while the critical temperature is the specific temperature at which a substance transitions from one phase to another (such as from liquid to gas). The critical temperature is a unique property of a substance and is independent of pressure.
374 degrees Celsius
Temperature does not directly affect critical pressure. Critical pressure is a characteristic property of a substance and remains constant regardless of temperature. At the critical point, the substance exists as a single phase, with distinct liquid and gas properties disappearing.

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.

It liquefy the gas at its critical temperature
Above Critical Pressure. This will depend on the gas and its temperature.
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.

This is known as the "Critical Temperature". For example, CO2 has a critical temp of 31.2 degrees C and NH3 has a critical temp of 132 degrees C
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 substance can be determined by conducting experiments to observe the temperature at which the substance transitions from a gas to a liquid under high pressure. This critical temperature is a key characteristic of the substance's phase behavior.
