Two different liquids of same mass are kept in two identical vessels, which are placed in a freezer that extracts heat from them at the same rate causing each liquid to transform into a solid. The schematic figure below shows the temperature T vs time t plot for the two materials. We denote the specific heat in the liquid status to be C_(L1) and C_(L2) for materials 1 and 2 respectively, and latent heats of fusion U_(1) and U_(2) respectively. Choose the correct option.

The schematic figure below shows the temperature T vs time t plot for the two materials. We denote the specific heat of metrials in the liquid (solid) states to be C_(L1) (C_(S1)) and C_(L 2) (C_(S2)) respectively

One end of a copper rod of uniform cross section and length 1.5 m is kept in contact with ice and the other end with water at 100^@C . At what point along its length should a temperature of 200^@C be maintained so that in the steady state, the mass of ice melting be equal to that of the steam produced in same interval of time. Assume that the whole system is insulated from surroundings: [L_("ice")=80 cal//g,L_("steam")=540 cal//g]

One end of a copper rod of uniform cross-section and of length 3.1 m is kept in contact with ice and the other end with water at 100° C . At what point along it's length should a temperature of 200° C be maintained so that in steady state, the mass of ice melting be equal to that of the steam produced in the same interval of time. Assume that the whole system is insulated from the surroundings. Latent heat of fusion of ice and vaporisation of water are 80 cal/gm and 540 cal/gm respectively
