What is the importance of critical pressure?
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.
What is pseudo critical pressure and temperature?
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.
What is a substance's critical point?
the temperature and pressure where the liquid state no longer exist is called the critical point
What solutes is most effective in lowering the vapor pressure of water MgCl2 CCl4 NaCl AlCl3?
AlCl3 is most effective in lowering the vapor pressure.
What temperature is it impossible to liquify a substance no matter the pressure?
Any temperature below 0 Kelvin or -273.15 Celsius is impossible. +++ ... Because it indicates the body in question contains no heat energy.
What is the importance of critical pressure?
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.
Does temperature affect critical pressure?
no
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 pseudo critical pressure and temperature?
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.
What is the importance of pressure?
It liquefy the gas at its critical temperature
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.
At what pressure gas will be convert into liquid?
Above Critical Pressure. This will depend on the gas and its temperature.
What is a substance's critical point?
the temperature and pressure where the liquid state no longer exist is called the critical point
What is critical pressure of diesel fuel?
18.6 ATM for diesel UDER ATMOSPHERIC PRESSURE AND TEMPERATURE.
What is the critical point called?
the temperature at which a gas can be liquified by lowering the temperature which is accompanied by applying pressure.
What is the entropy at critical point?
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
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.
