A vessel is partly filled with a liquid. Coefficients of cubical expansion of material of the vessel and liquid are `gamma_v` and `gamma_L` , then the volume unoccupied by the liquid will necessarily

Options

A. Remain unchanged if `gamma_(V)=gamma_(L)`
B. Increase if `gamma_(V)-gamma_(L)`
C. Decrease if `gamma_(V)-gamma_(L)`
D. None of above

Answer

B

Explanation

`DeltaV_(f)=DeltaV_(i)+(gamma_(V)V_(V)-gamma_(L)V_(L))DeltaT` If `gamma_(L)=gamma_(V)` then `gamma_(V)V_(V)-gamma_(L)V_(L)` will be positive For sure
