The critical pressure of a substance is the pressure corresponding to the critical point (or the critical state) of the substance. The critical point of a substance can be defined as the point on the temperature and pressure scale in which a liquid substance can coexist with its vapour.
In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. One example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist.
27 maj 2024 · The critical pressure of a substance is defined as the pressure required to liquefy a gas at its critical temperature. Beyond this point, no amount of pressure increase can revert the gas to a liquid state.
What is meant by the term critical pressure? What is the effect of increasing the pressure on a gas to above its critical pressure? Would it make any difference if the temperature of the gas was greater than its critical temperature?
15 lip 2023 · The temperature at which this occurs is called the critical temperature, and the pressure is called the critical pressure. The accompanying videos illustrate what happens experimentally in the case of Chlorine.
Critical pressure is the temperature above which, a gas cannot be converted to liquid even by application of pressure. At the critical temperature, the pressure required to convert the gas into liquid is known as the critical pressure.
2 lut 2011 · define the critical point. This is the unique thermodynamic state for which, at temperature T c, molar volume is and pressure, p c It is necessary only to prescribe two of these critical state parameters since the third is then automatically determined.
