1.	Passage-I: Materials expansion character depends on them being isotropic or anisotropic. The superficial and cubical expansion coefficients can be arrived at by the addition of linear expansion coefficient in the three dimensions. While studying the expansion of a solid or a liquid one should consider the expansion of the container also. Any hole in a conductor will become larger on getting heated up as one comments "expansion is a photographic enlargement". Each liquid has its own characteristics behaviour of change of temperature. When heated in a copper container ( gamma_( c) ) a liquid shows an expansion coefficient of C and in a silver container, it shows S. The linear expansion coefficient of the silver container is alpha then 3 alpha equal to
Answer» `( C - S + gamma_( c ) )` ` ( C - S - gamma_( c) ) /( 3)` ` C - S + ( gamma_(c ) )/( 3 )` `(1)/(3) ( C - gamma_( c) - S)` ANSWER :A
