Evaporation vs. Vaporization: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Evaporation is the slow transition of a liquid to gas at a temperature below boiling; vaporization is the rapid change from liquid to gas at boiling point.
Key Differences
Evaporation is a surface phenomenon where molecules at the surface of a liquid gain enough energy to become a gas. In contrast, vaporization can occur throughout the liquid, especially when it reaches its boiling point. Both involve a liquid turning into a gas, but the processes and conditions under which they occur differ significantly.

Evaporation typically occurs at temperatures below the boiling point of the liquid. It's a gradual process where only some molecules with sufficient kinetic energy escape into the air. Vaporization, however, occurs when a liquid reaches its boiling point, and it's a much more rapid and energetic process as the entire liquid can turn into gas.

The energy source for evaporation can be the ambient temperature or the liquid's surroundings. It's a cooling process since it involves the liquid's surface molecules, which are higher in energy, leaving the surface. Conversely, vaporization requires external heat to bring the entire liquid to its boiling point, and it's an energy-intensive process.

Evaporation can happen under a wide range of conditions and is a common natural phenomenon, such as the drying of wet clothes. Vaporization, on the other hand, is often observed during cooking, like when boiling water turns into steam. Both processes are essential in nature and technology but occur under different circumstances.

In evaporation, the rate at which the liquid turns into gas is influenced by factors like surface area, temperature, and humidity. In vaporization, the rate is mostly dependent on the heat supplied and the liquid's boiling point. Both evaporation and vaporization play crucial roles in phenomena like the water cycle and industrial processes.
