Question

How does atmospheric pressure affect evaporation?

Answer 1

We know that less evaporation is observed in high atmospheric pressure value. Although it's not one of the main causes of change in evaporation along with climate as well as the air pressure going through some observation which is as less evaporation is observed in higher pressure values.

Complete step-by-step answer: Evaporation is the type of vaporization which occur on surface of liquid as well as when it change from its liquid state to gas state and for such occurrence gas in the surrounding, liquid shouldn't be in a saturation with evaporating substance. When a liquid molecule is colliding with any of the other so they transfer energies from one into another by depending on how they could collide with one another.
Any molecule will enter the gas phase and escape if they absorb energy even enough so, in order to overcome vapour pressure. That states evaporation is a process where any substance gets converted from liquid to gas state with use of a heat energy. Since heat is absorbed during evaporation, it's an endothermic process example evaporation salt production, crystallization here water evaporates into water vapour.
Any change in state of substance occurs due to either increase or might be due decrease in temperature which results in either speed up or speed down the molecules. Whereas in solids all molecules vibrate against one another while they are widely packed in liquids and they move freely whereas in gaseous state they move around widely in great space same goes with pressurize by atmosphere.

Note: Note that evaporation along with processes such as condensation and precipitation is an important step in the earth water cycle. It’s about $90$ of moisture present in earth’s atmosphere which is due to evaporation meanwhile rest $106$ are due total transpiration and since $70$ of earth surface is covered by the ocean they are main source of water in atmosphere as well as evaporation of ocean water is too important in order to produce fresh water.
