Data table of water phase changes

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). WebThe simplest phase diagrams are pressure–temperature diagrams of a single simple substance, such as water. The axes correspond to the pressure and temperature. The phase diagram shows, in …

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. WebNov 23, 2015 · So why is Gibbs free energy zero for phase changes at constant temperature and pressure? It isn't necessarily. For example if you supercool liquid water to -10 degrees C, let the water freeze and do this in a way that the final state is solid water at -10 degrees C, the change in Gibbs free energy will be negative.
