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 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 temperature at which air becomes saturated called?
The Dew Point.
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.
For every liquid there is a temperature above which the kinetic activity of its molecules is so great that the attractive forces cannot keep them in a liquid state this temperature is called?
Critical 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.
What is difference between critical temperature and boiling point?
difference between critical temp and boiling point
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 the critical point called?
The critical point is called the point at which a function's derivative is zero or undefined. At this point, the function may have a local maximum, minimum, or an inflection point.
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 the critical temperature and pressure of CCl4?
For example from hydrogen critical point (-239,85 0C) to lithium critical point (2 950 0C).
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 does the critical point represent?
Critical point is also known as a critical state, occurs under conditions at which no phase boundaries exist. There are multiple types of critical points, including vapor-liquid critical points and liqui-liquid critical points.
What is intercritical annealing?
Intercritical annealing is where the metal is heated to between its lower and upper critical temperature point to allow partial transformation of the matrix into austenite followed by slow cooling or holding below the lower critical temperature point.
Which one is the highest temperature between 38 degrees celcius96 fahrenheit302 kelvin and the freezing point of water?
38ºC = 311ºK96ºF = 35.5ºC = 308.5ºK302ºK = 302ºKfreezing point = 0ºC = 273ºKSo, the highest temperature would be 38ºC
Which temperature scale has the highest value for the boiling point of water?
208 °F
