Is it true or false critical pressure is the pressure that will cause solid las to liquefy at the critical temperature?
False. Critical pressure is the pressure required to liquefy a substance at its critical temperature, but it does not refer to the pressure that will cause a solid to liquefy. At the critical temperature, a substance cannot exist as a liquid and vapor phase; therefore, the concept of solid melting into a liquid under critical pressure is not applicable.
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.
What is critical temperature of gasoline?
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.
Is it true that above the temperature no amount of pressure will casue a gas to liquefy?
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.
What is the critical pressure of seawater?
The critical pressure of seawater, which is the pressure above which water cannot exist as a liquid regardless of temperature, is approximately 22.1 megapascals (MPa) or about 220 atmospheres. This value can vary slightly depending on the salinity and temperature of the seawater. At this pressure, seawater transitions to a supercritical fluid state, exhibiting properties of both liquids and gases.
What is critical pressure of diesel fuel?
18.6 ATM for diesel UDER ATMOSPHERIC PRESSURE AND TEMPERATURE.
What is the critical temperature of diesel fuel?
The critical temperature of diesel fuel is typically around 400-450 degrees Celsius. Above this temperature, diesel fuel can vaporize and pose a serious fire hazard. It is important to handle and store diesel fuel carefully to prevent accidents.

False. Critical pressure is the pressure required to liquefy a substance at its critical temperature, but it does not refer to the pressure that will cause a solid to liquefy. At the critical temperature, a substance cannot exist as a liquid and vapor phase; therefore, the concept of solid melting into a liquid under critical pressure is not applicable.
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 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 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 dimethyl sulphoxide?
447_c is the critical temp of dimethyl sulphoxide
What is the importance of pressure?
It liquefy the gas at its critical temperature
At what pressure gas will be convert into liquid?
Above Critical Pressure. This will depend on the gas and its temperature.
What refers to the temperature above which a gas cannot be liquefied by an increase in pressure?
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
What is critical temperature of gasoline?
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.
