Question

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 1

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.

Answer 2

Answer:

(D) on the physical state of molecules in the bulk phase

Explanation:

The interface is the border between two areas of space occupied by distinct matter or matter in distinct physical states. The interface's importance depends on the type of system: the greater the area or the volume of the quotient, the greater the interface effect.

Thus, it is surface that separates two stages of matter, each of which can be solid, liquid or gaseous. An interface is not a geometric surface, but a thin layer with properties on either side of the interface that differ from those of the bulk material.
