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.

15 lip 2023 · The following table lists the critical temperatures and critical pressures for some well-known gases and liquids. Such data are often quite useful. Many gases are sold commercially in strong steel cylinders at high pressures.
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.
29 sty 2018 · Here we examine the molecular structure of liquid water across its range of stability, from mild supercooling to the negative pressure and high temperature regimes.
The critical pressure \(\left( P_\text{C} \right)\) is the pressure that must be applied to the gas at the critical temperature in order to turn it into a liquid. The critical point is the intersection point of the critical temperature and the critical pressure.
When water vapour and liquid water coexist at equilibrium, the partial pressure of water is uniquely defined at a given temperature—it is the saturation vapour pressure. Thus, the line on Figure 8.2 can be considered as a phase line. As temperature is changed, the partial pressure of water will simply move up and down this – – = (8.4)
The critical temperature (T c ) of a substance is the highest temperature at which the substance can possibly exist as a liquid. The critical pressure (P c ) is the pressure that must be applied to the gas at the critical temperature in order to turn it into a liquid.
