1.	Two identical vessels are filled with equal amounts of ice. The vessels are made from different materials. If the ice melts in the two vessels in times `t_(1) and t_(2)` respectively, then their thermal conductivities are in the ratioA. `t_(1)/t_(2)`B. `t_(2)/t_(1)`C. `t_(2)^(2):t_(1)^(2)`D. `t_(1)^(2):t_(2)^(2)`
Answer» Correct Answer - B `mL=(KA(theta_(1)-theta_(2))t)/(d)` in the given problem, `Kt = consta nt` `:. (K_1)/(K_2)=(t_2)/(t_1)`.
