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 the liquefaction point of oxygen gas?
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.
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.
Formulae to find velocity using pressure?
p=F/A,where p=pressure,f=force,A=areaF=ma,m=mass, a=accelerationp=ma/Aa=v/tp=(mv/t)/A(pAt)/m=vtherefore,v = (pAt)/m
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 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 the critical level of a backflow preventer?
the critical level of a backflow preventer is the point at which the outgoing pressure exceeds the incoming pressure
What is difference between 500MW boiler 660MW boiler?
500 MW Boiler is sub-critical Boiler which generates steam at pressure lower than the critical pressure ie below 221.2 kg/sqcm. where as the 660 MW boiler is super critical boiler which operates steam pressure above critical pressure.
Does temperature affect critical pressure?
no
What is an example of critical in a sentence?
The patient's blood pressure had reached critical levels.
What is critical flow in fluids?
Critical flow exists when at a fixed upstream pressure the flow cannot be further increased by lowering the downstream pressure. Flow is proportional to the square root of the pressure drop.
At what pressure gas will be convert into liquid?
Above Critical Pressure. This will depend on the gas and its temperature.
What is the importance of pressure?
It liquefy the gas at its critical 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 are critical and super critical boilers?
critical boiler operating steam parameter 221.12bar and 375 centigrate . you can rise in pressure and temperatureabove the critical point. that is called supercritical boiler.
