A critical temperature is the temperature at which a substance transitions between different phases (solid, liquid, gas) under specific conditions, such as pressure. Above this temperature, the substance cannot exist in a distinct phase and becomes a supercritical fluid. It is a fundamental property for understanding phase transitions in materials.

What is the critical temperature of dimethyl sulphoxide?
447_c is the critical temp of dimethyl sulphoxide
What is difference between temperature and critical temperature?
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.
What is pseudo critical pressure and temperature?
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.
What is the critical temperature of steel?
The critical temperature of steel is typically around 723°C (1,333°F). This is the temperature at which steel undergoes a phase change from a non-magnetic state to a magnetic state, known as the Curie temperature.
What is the importance of critical pressure?
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.
What is the critical temparature?
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.
What is the critical temperature of dimethyl sulphoxide?
447_c is the critical temp of dimethyl sulphoxide
What is the critical temperature of oxygen?
the critical temperature of oxygen is -118.6 C/ -155 F
How can one determine the critical temperature of a substance?
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.
Does temperature affect critical pressure?
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.
What is difference between temperature and critical temperature?
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.
Why critical temperature is lower than melting temperature?
the critical temperature is for the phase stability? When the phase changes,the energy needed is smaller than the material melton,
What is lower critical temperature?

What are properties of critical temperature?
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 .
What is pseudo critical pressure and temperature?
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.

What is the definition of critical Temperature of a Refrigerant?
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.
Why boiler is operated close to critical temperature?
Greatest efficiency at that temperature.
