Two identical conducting rods are first connected independently to two vessels, one containing water at 100 C and the other containing ice at 0 C. In the second case the rods are joined end to end and connected to the same vessels. Let Q1 and Q2 be the rate of melting of ice in the two cases respectively. Then the ratio Q 2/Q1 is :

A cylindrical rod with one end in a steam chamber and the other end in ice results in melting of 0.1 gm of ice per second. If the rod is replaced by another rod with half the length and double the radius of the first and if the thermal conductivity of the material of the second rod is 1/4 times that of first, the rate at which ice melts in gm/second will be :

A wall is made up of two layers A and B. The thickness of the two layers is the same, but materials are different. The thermal conductivity of A is double than that of B. In thermal equilibrium the temperature difference between the two ends of wall is 36 C. Then the difference of temperature at the two surfaces of A will be
