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 :

Two rods of the same material have diameters in the ratio 1:2 and the lengths in the ratio of 2:1. If the temperature difference between their ends is the same ,
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 :
