Question

2 point on evaporation

Answer 1

☆ This phenomenon is also called evaporative cooling.

☆ This is the reason that evaporating sweat cools the human body.

☆the thermal motion of a molecule of liquid must be sufficient to overcome the surface tension and evaporate, that is, its kinetic energy must exceed the work function of cohesion at the surface.

☆Evaporation therefore, proceeds more quickly at higher temperature, at higher flow rates between the gaseous and liquid phase and in liquids with lower surface tension (i.e. higher vapor pressure).

Answer 2

in evaporation the process of formation of vapour from the liquid takes place in any temperature generally below the boiling point second. It generally causes to cooling hey are the two points on the evaporation I hope it will help you thank you
