no no ,, i think the answer is C ,,, cuz after evaporation the most energetic particles have escaped taking the energy wid them . which in turn decreases the temperature of the remaining liquid .. its just like an after shave which after it evaporates leaves the skin cool ...

well i personally put down C ,, ppl people say its B cuz some crossectional area bullshit ,,i just dont get how its B , i think its C
astarmathsandphysics:
It is B. The cross sectional area is different but the pressure is the same using P=pgh(=atmospheric pressure)
