Evaporation Is A Fundamental For Human Life

Evaporation is eminently fundamental for the human life. Without evaporation, there would be no crops, no rain, and the human body would overheat. When most people think about evaporation, they usually associate it with the water cycle. All liquids can evaporate at room temperature, including water, orange juice, rubbing alcohol, and nail polish remover, but do they all evaporate at the same rate? Surprisingly, most people do not take into consideration that evaporation also occurs in their own home. Evaporation is one of the six stages of the water cycle, or hydrologic cycle. Evaporation is the process in which a liquid surpasses a change to become a gaseous substance. Evaporation befalls due to atoms or molecules escaping from a liquid…show more content…
The average energy can be low and the evaporation still continues.” (United States Geological Survey 2014) Not all molecules have the same energy, which is why evaporation can occur even if the liquid isn’t boiling. The rate of evaporation is increased with a decrease in the gas pressure around a liquid. Once the gas pressure reaches a specific level, the rate of evaporation slows down. The density of a liquid also has an impact on the rate of evaporation; the higher the density of a liquid, the slower the rate of evaporation. The most important substance in the world is water, without it there would be no world. Water is a molecule that is composed of two hydrogen atoms and one oxygen atom, also known as H2O. Water is a polar molecule, making it able to dissolve other polar molecules. Water is attracted to itself by cohesion. Cohesion is the attraction of one substance to itself. Cohesion is possible for water due to its strong hydrogen bonds. Alone hydrogen bonds are weak, but together they form one of the strongest bonds known. Water is an extremely diverse substance that can be in solid form, liquid form, and gas form. The normal temperature of water is 25oC, which produces its liquid form. When water reaches below 0oC, it freezes and becomes solid. Above100oC is when water reaches its gaseous form and boiling point; that is more than a 75o temperature change from liquid to gas. Studies show that the evaporation rate of a liquid depends on the
