The critical temperature and critical pressure of a substance define its critical point, beyond which the substance forms a supercritical fluid. Conceptual Problems Describe the changes that take place when a liquid is heated above its critical temperature.

The critical point of liquid water is at 650°K (with a much higher pressure than you care to create in space: 22MPa), which is only 450° above the sublimation temperature. But the water should be cooled by 540° to provide enough heat to evaporate completely.
15 lip 2023 · What happens when a gas becomes so dense it can no longer be called a gas? Here we learn about a special instance where the line between liquid and gas are blurred: critical temperature and pressure.
The critical temperature and critical pressure of a substance define its critical point, beyond which the substance forms a supercritical fluid. Conceptual Problems Describe the changes that take place when a liquid is heated above its critical temperature.
At the critical point, defined by a critical temperature T c and a critical pressure p c, phase boundaries vanish. Other examples include the liquid–liquid critical points in mixtures , and the ferromagnet–paramagnet transition ( Curie temperature ) in the absence of an external magnetic field.
1 sie 2023 · Clusters of certain shape are predicted to be thermodynamically stable at ambient down to supercooled conditions and their presence almost quantitatively explains water’s anomalous properties as a function of temperature and pressure.
As the temperature and pressure approach the critical point, the properties of the liquid and gas become progressively more similar. At the critical point, the liquid and gas become indistinguishable. Above the critical point, there are no longer separate liquid and gas phases: there is only a generic fluid phase referred to as a supercritical ...
