What are the different methods that are being used in the process of evaporation? Explain the methods with examples. Please answer at your own easy words.
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.

Technically speaking, evaporation is the process of turning a liquid into a vapour in order to separate it from another liquid with a higher boiling point or from a solid that has been dissolved in it. Water is the liquid that evaporates most frequently.
Methods of Evaporation:
There are some methods that are being used for the evaporation process.
1. spontaneous airborne evaporation.
This method involves exposing very large liquid surface areas to spontaneous evaporation in the open air, is relatively slow. The amount of time required depends on the air's temperature, humidity, and how thoroughly the vapours are evacuated from the liquid's surface. Water evaporates relatively quickly in hot, dry weather, especially if a strong breeze is blowing.
This method is solely applied to the production of salt from natural brines or seawater. Significant amounts of salt are created in several warm countries in this manner.
