Thermal Expansion of different materials

A fluid having a thermal coefficient of volume expansion gamma is filled in a cylindrical vessel up to a height h_0 . The coefficient of linear thermal expansion of the material of the vessel is alpha . If the fluid is heated with the vessel , then find the level of liquid when temperature increases by Deltatheta .

A slab consists of two parallel layers of two different materials of same thickness having thermal conductivities K_(1) and K_(2) . The equivalent conductivity of the combination is
