This natural occurrence is called evaporation. Evaporation is the vaporization that occurs on the surface of a liquid that is not boiling. Evaporation and vaporization can be easily confused, because they are both the conversion of a liquid to a gas or vapor. However, vaporization only occurs when the liquid is boiling, while evaporation only occurs on liquids that are not boiling. Water begins to evaporate at 0 degrees Celsius, and then starts to vaporize at 100 degrees Celsius (water's boiling point). Evaporation is a fundamental part of the water cycle and is constantly occurring throughout nature.]]> 2017-04-13 15:57:38 UTC https://padlet.com/obryan_ri_a/8vfhzctbel6e/wish/166277871 obryan_ri_a https://padlet.com/obryan_ri_a/8vfhzctbel6e/wish/166284099 Evaporation and kinetic energy are directly related because the faster the molecules are moving, the faster the liquid evaporates. Most of the molecules in a liquid don't have enough kinetic energy to escape into the gaseous state. Only certain molecules with a specific minimum kinetic energy can escape from the surface of a liquid, however even these molecules can collide with air particles and be rebounded back into the liquid. Liquids evaporate faster when they are heated. This is true because heating the liquid increases the kinetic energy of its particles. As evaporation occurs, particles with the highest amount of kinetic energy escape first, leaving the particles with a lower kinetic energy as a liquid. Because heat increases kinetic energy, the particles that are the most heated evaporate, resulting in an overall decreased temperature of the liquid. Therefore, evaporation can be seen as a cooling process. ]]> 2017-04-13 16:28:09 UTC https://padlet.com/obryan_ri_a/8vfhzctbel6e/wish/166284099 obryan_ri_a https://padlet.com/obryan_ri_a/8vfhzctbel6e/wish/166285651 2017-04-13 16:37:16 UTC https://padlet.com/obryan_ri_a/8vfhzctbel6e/wish/166285651
