1.	(1) Consider the following cases- The nature of flow of energy in case (I) is same as that in- (A) II , (B) III , (C ) II and III, (D) None
Answer» Solution :(D) None, Because in `II` and `III`, the flow of ENERGY or MATTER is taking place only in one direction.While in EQUILIBRIUM STATE, the flow of energy takes place in both DIRECTIONS equally. Thus `(I)` is a dynamic equilibrium while states in `II` and `III` are called steady state (static equilibrium).
