1.	If gamma_(R) , gamma_(A) and gamma_(V) represent the coefficient of real expansion of a liquid, coefficient of apparent expansion, n of the liquid and coefficient of cubical expansion of the material of the vessel respectively, then which of the following is/are correct?
Answer» `gamma_(A)` is +ve `gamma_(A)` is -ve `gamma_(A)` is ZERO `gamma_(A)` is NEVER -ve Answer :A::B
