Among gases and liquids which diffuses faster and why? Justify with the help of an example of both.

Dear student,

Molecules of gas move faster than liquid as:
a) Molecules of gas are more widely spaced than liquids.
b) They are free to move as they do not have fixed volume. 

Thus, moelcules of gas will diffuse faster.
Ex:- If you spray perfume in one corner of a room, you can still smell it everywhere in the room as perfume is in gaseous form.
Water filled in a glass on the table will be confined in the particuar volume of glass only.
