The ends of the cups were closed with corks through which two mercury manometers were connected. After a few hours, $CaCl_2$​​​​​​​ vials were taken out and weighed again.

(i) What is the purpose of keeping $CaCl_2$ vials inside the cup?
(ii) After a few hours, the $CaCl_2$ vials were taken out and weighed again. Will you expect any difference in weight? If so, give reasons.
