A piece of metal floats on mercury. The coefficients of volume expansion of the metal and mercury are `gamma_(1) and gamma_(2)` respectively. If the temperature of both mercury and metal increased by an amount `Delta T`, the fraction the volume of metal submerged in mercury changes by the factor.

A

`(1)/( ( gamma_(2) - gamma_(1) ) Delta t) `

B

`( 1)/( ( gamma_(2) - gamma_(1) ) Delta t) `

C

`( gamma_(1) - gamma_(2) ) Delta t`

D

`( gamma_(2) - gamma_(1) ) Delta t`

A piece of metal floats on mercury. The volume coefficient of expansion of the metal and mercury are gamma_(1)andgamma_(2) respectively. If the temperature of both mercury and metal are increased by DeltaT , by what factor does the fraction of the volume of the metal submerged in mercury change?

The apparent coefficient of expansion of a liquid when heated, filled in vessel A and B of identical volumes is found to by gamma_(1) and gamma_(2) respectively. If alpha_1 be the linear expansivity of A then that of B will be:
