4 lis 2012 · Critical Pressure: The pressure required to liquify a substance vapor at its critical temperature. Critical point: The end point of the pressure-temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas cannot be liquefied by pressure alone.

4 lis 2012 · At the critical point water and steam can't be distinguished and there is no point referring to water or steam. The critical point of water is achieved at Water vapor pressure of 217.75 atm = 220.64 bar = 22.064 MPa = 3200.1 psi
The critical point of water occurs at 647.096 K (373.946 °C; 705.103 °F) and 22.064 megapascals (3,200.1 psi; 217.75 atm; 220.64 bar). [ 3 ] In the vicinity of the critical point, the physical properties of the liquid and the vapor change dramatically, with both phases becoming even more similar.

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 point of water is known to occur at a temperature point of 647 Kelvin (which is equal to 374 degrees celsius and 705 degrees fahrenheit) and a critical pressure of 22.064 MPa (which is roughly equal to 218 atmospheres of pressure).
