One end of a cylindrical rod is kept in steam chamber and the other end in melting Ice. Now `0.5gm` of ice melts in `1sec` if the rod is replaced by another rod of same length half the diameter then rate of melting of ice will be (in gm/sec) .

One end of a cylindrical rod is kept in steam chamber and the other end in melting Ice. Now 0.5 gm of ice melts in 1 sec. If the rod is replaced by another rod of same length, half the diameter and double the conductivity of the first rod, then rate of melting of ice will be

One end of a metal rod is dipped in boiling water and the other is dipped in melting ice.

One end of a metal rod is dipped in boiling water and the other is dipped in melting ice.

One end of a metal rod is dipped in boiling water and the other is dipped in melting ice.

A cylindrical rod with one end in a steam chamber and the other end is in ice It is found that 1gm of ice melts per second If the rod is replaced by another one of same material double the length and double area of cross section, The mass of ice that melts per second is .

A cylindrical rod with one end in a steam chamber and the other end in ice results in melting of 0.1 g 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 material of the second rod is 0.25 times that of first, the rate at which ice melts in gs^(-1) will be:
