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)`respectively. If the system is heated, then volume unoccupied by the liquid will necessarily :

Options

A. increase if `gamma_(V)gtgamma_(L)`
B. decrease if `gamma_(V)ltgamma_(L)`
C. remains unchanged if `gamma_(V)=gamma_(L)`
D. increase if `gamma_(V)=gamma_(L)`
