Subject: Evaporation rate for bottles with different sizes of neck openings,

Dear Sir/Madam,
              I have a question which my sister has been asking me and I wasn't 
sure of the answer. The question goes like this: Given a number of bottles 
filled up with the same amount of water, but with different sizes of neck 
openings, which bottle will allow the maximum evaporation rate. Will the 
evaporation rate be the same for all the bottles or will it be dependent on the 
size of the neck opening? I have a asked some of my friends but they are not 
sure. Kindly enlighten me on this so that I would be able explain to my younger 
sister on this issue. Thanks a million. 
Have a nice day.
