the temperature which occupied to liquefy the gas at its critical pressure and critical volume ,it is represented by Tc.

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.
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 .
Does refrigerant enter the compressor as a low temperature low pressure gas?
Yes. The basic components of the refrigeration system are the refrigerant, compressor, condenser and receiver, expansion device and the evaporator. One cycle: Refrigerant travels to Compressor (A) to Condenser (B) to Expansion device (C) to evaporator (D). The refrigerant gas at low pressure and temperature is drawn into the compressor. The gas is compressed to a higher pressure, which causes an increase in the temperature. The refrigerant gas at a high pressure and temperature passes to the condenser (point B), where it is cooled (the refrigerant gives up its latent heat) and then condenses to a liquid. The high pressure, low temperature liquid is collected in the receiver. The high pressure liquid is routed through an expansion valve (point C), where it undergoes an abrupt reduction in pressure. That pressure reduction causes part of the liquid to immediately vaporize or flash. The vapor and remaining liquid are cooled to the saturation temperature (boiling point) of the liquid at the reduced pressure. At this point most of the refrigerant is a liquid. The boiling point of the liquid is low, due to the low pressure. When the liquid refrigerant enters the evaporator (point D), it absorbs heat from the process and boils. The refrigerant gas is now at low pressure and temperature, and enters the suction side of the compressor, completing the cycle.
When removing oil from a low pressure system the temperature should be 130 degrees f because?
Less refrigerant will be contained in the oil at the higher temperature
What is the short version of the definition of weather?
The short Version of the Definition of Weather is: temperature.
Should refrigerants be operated at temperatures above or below their critical temperature?
The critical temperature of a refrigerant is the point at which it changes states. In a refrigeration scenario, this happens 2 times per cycle. The refrigerant is a liquid on the high pressure side, and below its critical temp. On the low pressure side it becomes a vapor (gas) and its above its crictal temp. So the answer is both, depending on what side of the system you are on.
How do you change high temperature refrigerant and high pressure refrigerant in to low temperature refrigerant and low pressure refrigerant?
You cool it and run it through a metering devise.
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 definition of critical angle?
The definition of critical angle is the angle of incidence that refraction can still occur.
What is the critical temperature of oxygen?
the critical temperature of oxygen is -118.6 C/ -155 F
Define temperature glide as it pertains to refrigerant blend?
The temperature glide occurs when the refrigerant "blend" has "various" temperatures as it evaporates and condenses at a single given pressure.
Temperature glide in an zeotropic refrigerant menas the refrigerant is a?
a mixture of two or more substances of different properties.
What is the condensing pressure?
According to state of the outlet refrigerant from compressor, it's better we use refrigerant temperature.
What the definition of critical cooling rate in a context of austenite transformation?
The slowest rate of cooling from the hardening temperature which will produce the fully hardened martensitic condition.
What determines the temperature at which a refrigerant vaporizes?
pressure / temperature / volume /enthalpy
What is the chiller condenser pressure?
According to state of the outlet refrigerant from compressor, it's better we use refrigerant temperature.
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.
