Evaporation results in lowering of temperature. The temperature may be lowered or remains constant in vaporization. Vapour pressure is lower than external pressure. Vapour pressure may be lower or same as external pressure in evaporation and boiling respectively. Heat source is not required for the process. A heat source may or may not be required depending on the process. On signing up you are confirming that you have read and agree to Terms of Service.
What You'll Learn? Spread the Differences. Vaporization Evaporation Vaporization is defined as the transitional phase of a compound or an element and it occurs during the boiling or sublimation process. Evaporation is nothing but a type of vaporization which mostly occurs at temperatures below the boiling point.
During evaporation, the liquid state of matter is turned directly into a gas. Evaporation is generally a slower process and requires more energy as the molecules have a high tendency to convert into the vapor phase. As for evaporation, only the top level of water is turned into gas. During evaporation, the molecules vaporize only from the surface of the liquid. Like Dislike Related Differences.

The liquid molecules that evaporate must be located at the surface of the water and have enough kinetic energy to evaporate. An increase in temperature, surface area or air movement will increase the rate of vaporization. As the pressure increases, however, it is more difficult for particles to gain kinetic energy and escape, and vaporization will decrease.
Water at a lower elevation, where there is more pressure, takes longer to boil. In a closed system, such as a water bottle, water will evaporate, often touch the edges of the water bottle, then condense and fall back into the body of water. The vapor pressure, the pressure of the a vapor in contact with its liquid form, increases in the water bottle until the pressure reaches a certain point that discourages further evaporation.
If water is boiled in a pot, the vapor pressure can become strong enough that it can cause the closed system to burst open, such as the rattling or lifting of a pot lid.

Consider these definitions to distinguish between vaporization and evaporation. With heat, low humidity, quicker air movement and lower pressure, evaporation increases. Kinds of Precipitation. What Does the Condensation Process Require?
