1.	On which does the interface depend? Select the proper choice from the given choices. (A) on the volume of molecules in the bulk-phase (B) on the weight of molecules in the bulk phase (C) on the number of molecules in the bulk phase (D) on the physical state of molecules in the bulk phase
Answer» it's MAY be on the NUMBER of molecules in the bulk PHASE. or may be on the weight of molecules in the bulk phase. I am not SURE it may be B or C only.
