Thermodynamic properties of water: Boiling temperature (at 101.325 kPa): 99.974 °C = 211.953 °F. Bulk modulus elasticity : 2.15 x 10 9 Pa or N/m 2. Critical temperature : 373.946 °C = 705.103 °F.
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.
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. For water, the critical pressure is very high, \(217.75 \: \text{atm}\).
The critical pressure of a pure substance is defined as the pressure above which liquid and gas cannot coexist, regardless of the temperature. With multicomponent mixtures, these properties are referred to as pseudo critical temperature and pseudo critical pressure.
11 wrz 2022 · The critical point for water is 647.096 K (373.946 °C; 705.103 °F) and 22.064 megapascals (3,200.1 psi; 217.75 atm). This is a higher temperature and pressure than water’s triple point. Near the critical point, liquid water becomes compressive, a poor dielectric, and a poor solvent for electrolytes.
