Question

removal of water from mixture by freezing drawing involves cooling below 0°C reduction of pressure below the triple point and subsequent warming. how do you explain in terms of phase diagram of water ​

Answer 1

Evaporation is a phase transition from the liquid phase to the gas phase that occurs at temperatures below the boiling point at a given pressure.

For molecules of a liquid to evaporate, they must be located near the surface, be moving in the proper direction, and have sufficient kinetic energy to overcome liquid-phase intermolecular forces.

Boiling is a phase transition from the liquid phase to the gas phase that occurs at or above the boiling temperature.

Boiling is the rapid vaporization of a liquid and occurs when a liquid is heated to its boiling point. A liquid’s boiling point is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environment (air).
