WebAt 373.99°C, particles of water in the gas phase are moving very, very rapidly. At any temperature higher than that, the gas phase cannot be made to liquefy, no matter how much pressure is applied to the gas. 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. WebWe can use the phase diagram to identify the physical state of a sample of water under specified conditions of pressure and temperature. For example, a pressure of 50 kPa and a temperature of −10 °C correspond to the region of the diagram labeled “ice.”. Under these conditions, water exists only as a solid (ice). dark urine and jaundice https://atucciboutique.com
