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» 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). |
