1.	A solid whose volume does not change with temperature floats in a liquid. For two different temperatures t_1 and t_2 of the liquid, fractions f_1 and f_2 of the volume of the solid remain submerged in the liquid. The coefficient of volume expansion of the liquid is equal to
Answer» `(f_1 - f_2)/( f_(2) t_(1) - f_(1) t_(2) ) ` `( f_(1) - f_(2) )/( f_(1) t_(1) - f_(2) t_(2) )` `( f_(1) + f_(2) )/( f_(2) t_(1) + f_(1) t_(2) )` `(f_(1) + f_(2) )/( f_(1) t_(1) + f_(2) t_(2) )` ANSWER :A
