What affects evaporation rate?! Wind speed- The stronger the wind, the more rapid theevaporation.- Why? - Stronger wind over surface blowsaway vapor molecules from nearsurface, so they will not re-enter enter liquidsurface.- Example - Clothes dry out faster in thewind, we feel colder in the wind withwet clothes
! Temperature of the water– The higher the water temperature, themore rapid the evaporation.- Why? - The higher temperature means thatwater molecules in the liquid are movingfaster, and will escape to form vapor.- Example - wet clothes dry faster in the sun
