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 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 :

then the ratio of heats conducted by them in a given time will be : 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
