Which best explains the relationship between evaporation and temperature? A liquid evaporates slower at lower temperatures because the molecules are more spread apart and are not pushed as easily from the liquid’s surface. A liquid evaporates faster at lower temperatures because the attractions are decreased and more particles can escape the surface of the liquid. A liquid evaporates slower at higher temperatures because the vapor pressure of the liquid is higher, so fewer molecules can escape the surface. A liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid
