A cylindrical copper rod of length 1.2 m and crosssectional

area 4.8 cm2 is insulated to prevent heat loss through its
surface. The ends are maintained at a temperature difference of
100 C° by having one end in a water – ice mixture and the other in
a mixture of boiling water and steam. (a) At what rate is energy
conducted along the rod? (b) At what rate does ice melt at the
cold end?

u just need to know the speceic cunductance of copper and latent heat heat of usion of ice..

Now here

100=L*dq/dt/K*A

from here u can get dq/dt

which would rate of heat lose

And equating dq/dt = M*L

u will get mass of ice converting to water per second
