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 ratio:

Options:

Answer:

Solution:

For the same heat, $t \propto \frac{1}{k}$ . So $\frac{k _{1}}{k _{2}} = \frac{t _{2}}{t _{1}}$ . B.
