On the basis of the distribution of kinetic energies of the molecules in a liquid, explain why increasing the liquid's temperature increases the rate of evaporation. Select all that apply. O The molecules with low kinetic energy are the first to evaporate. O The molecules with high kinetic energy are the first to evaporate. O As the temperature increases, the average kinetic energy of the molecules increases. O As the temperature increases, a larger fraction of the molecules have sufficient energy to escape from the liquid. O As the temperature increases, a smaller fraction of the molecules have sufficient energy to escape from the liquid. O None of these. eTextbook and Media Save for Later Attempts: 0 of 15 used Submit Answer МacBook Air 吕0 888 F5 F6 F7 F8 F9 F10 F3 F4 F2
