Vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation. Heat must be supplied to a solid or liquid to effect vaporization.
The lines between different phases signify a set of points where the phases are in equilibrium. The sublimation curve (yellow) shows when both solid and vapor.
For distillation, both vapor and liquid compositions are of interest. Thus we combine the liquid composition diagram and vapor composition diagram into one.

Vaporization of a sample of liquid is a phase transition from the liquid phase to the gas phase. There are two types of vaporization: evaporation and boiling.
Such is an example of a dynamic equilibrium, the status of a system in which reciprocal processes (for example, vaporization and condensation) occur at equal rates. The pressure exerted by the vapor in equilibrium with a liquid in a closed container at a given temperature is called the liquid’s vapor pressure (or equilibrium vapor pressure).
In the previous module, the variation of a liquid's equilibrium vapor pressure with temperature was described.
Physical changes, such as phase transitions, are also reversible and may establish equilibria. This concept was introduced in another chapter of this text through discussion of the vapor pressure of a condensed phase (liquid or solid).

At saturation, condensation equals evaporation, and since evaporation is greater, condensation must be greater as well.

Note: along the two-phase coexistence (equilibrium) curves in which one of the coexisting phases is a gas, p refers to the vapor pressure of the substance.
Vaporization (or vaporisation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization: evaporation and boiling evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon.

As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase. The change from the gas phase to the liquid is called condensation.

This equations states that the slope (rise/run) of an univariant equilibrium plotted on a p-t diagram is equal to the entropy change ( δ s) of the reaction divided by the volume change ( δ v) of the reaction. Using the clapeyron equation, only the slope of the equilibrium is determined, not the actual position of the reaction in pressure-temperature space.
For example, the transition form liquid to gas is called vaporization. Vaporization is endothermic (uphill in energy), and this transition leads to an increase in entropy. The reverse transition of a gas going to a liquid is condensation. Since condensation is simply the reverse of vaporization, the changes in enthalpy and entropy will be exactly the same, but opposite in sign.

• it means: • raoult’s law can apply only for low to moderate pressures. • raoult’s law can apply only when the species that comprise the system are chemically similar.
Vaporization is also a process of changing the physical state of a substance in vapor phase and is one of a number of techniques involving phase equilibria. The vaporization (or evaporation) term typically refers to changing the state into vapor phase below the boiling temperature of a liquid.
Melting curve is the curve in the phase diagram along which solid and liquid phase of a system stays in equilibrium. Liquid and gas phase of a system stay in equilibrium along the vaporization curve while sublimation curve represents the equilibrium stage between solid and gas phase.
